Fix big emoji disappearing in production builds
An emoji-only message stopped rendering big and animated once built — in dev it
was always fine, which is what made it look like a settings or server problem.
src/vendor/emoji/regex.ts held lone surrogates in its string value: the upstream
pattern splits astral emoji across alternations, so '\uD83C[\uDFFB-\uDFFF]' has
a high surrogate with nothing to pair with. Rolldown folds that constant into
the bundle and re-encodes it as UTF-8, where a lone surrogate has no
representation — in index.worker-*.js every one of them came out as U+FFFD
followed by the leftover "d83c", 1246 times. Evaluating the shipped pattern
confirms it: 😳 🔥 👍 😀 no longer match, while ❤ ☝ ⌚ still do, because those
are BMP and were never written as surrogates.
So the worker's FULL_REG_EXP produced no messageEntityEmoji for any astral
emoji, totalEntities carried none, and bubbles' emojiStrLength === strLength
test could never hold — bigEmojis stayed 0, no .emoji-big, no animated sticker.
Only the worker chunk was affected, which is why the input's own suggestions
kept working: those are parsed on the main thread.
The literal is pure ASCII now — every \u and \x backslash is doubled, so the
escapes stay text and RegExp resolves them itself when the pattern compiles.
Same matching, and nothing left in the string for a bundler to mangle. A test
pins both halves: the source stays ASCII, and parseEntities still returns an
emoji entity spanning the whole emoji. A clean build has zero U+FFFD in any
chunk.

Stop rebuilding the emoji suggestions for an emoji already suggested
Typing 😳 into an input that already ended in 😳 tore the suggestion strip down
and built it again from scratch: a fresh searchCustomEmoji, a new container for
every item, replaceWith, and the scroll back at zero — all to arrive at exactly
what was on screen.
checkAutocomplete only guards against an unchanged value, but the emoticon is
derived from it: getCustomEmojiSuggestionEmoticon slices from the emoji entity
that ends at the caret, so a longer value can still name the same emoji.
checkEmoticon took it from there unconditionally.
It returns early now when the emoticon matches the one already on screen. The
helper has to be visible for that — hidden means the strip was torn down and
must be rebuilt, and it also covers an in-flight request that a hide cancelled.
A different emoticon, or a `:query` search (which clears this.emoticon), still
renders as before.

Show a video chat plate under the topbar for group calls you haven't joined
The topbar already had a plate for RTMP live streams, but an ordinary group
video chat had no entry point besides the header button. Add a sibling plate
laid out like the other clients: icon and title on one side, the join button
on the other, and a three-face preview of who is already in the call centred
on the plate.
The stack is centred with equal-basis side columns rather than absolute
positioning, so it sits on the real centre (as tdesktop paints it at
`width / 2`) while a long call title can never run under it. On handhelds the
stack shrinks so holding the centre does not clip the participants counter.
Visibility follows every other client: `call_active` + `call_not_empty`, the
call is not an RTMP stream (that one belongs to the live plate), and we have
not joined it ourselves. The joined edge comes from the controller's
`instance` event and the closing edge from the instance's own `state` event,
since the controller keeps its reference after a hang-up.
`getGroupCallPreview` gives the plate the call plus the first N participant
peers in one hop, so the whole participants map never crosses the worker
boundary, and only chats that actually have a call subscribe to the full peer.

Lay the Requests plate out like the translation one
The join-requests plate was the only floating plate still built as a
full-bleed clickable row: faces pinned to the start, title floating in
the middle, close button inside the same ripple area. Give it the shape
every other plate already has — the stretched, centred pill of the
translation plate, with the faces taking the start slot exactly the way
the close button takes the end one, so neither shifts the label off the
plate's centre. The width formula both plates now share moved into
`--pc-centered-button-width`.
Along the way:
- the label never carried `pinned-requests-title`, so its primary colour
and bold weight were dead CSS; it inherits both from the pill now, and
gets `text-overflow-no-wrap` so a large count ellipsizes instead of
wrapping out of the fixed 48px plate;
- the controller reported `height: 52` while the plate has always been
48 CSS px, which made `setFloating` reserve 4px too much;
- avatars go 32 -> 40px, matching the buttons on the plate, and shrink
back on handhelds where the centred label would otherwise run under
them (same trade-off as `.pinned-group-call`);
- the close button is no longer nested inside the clickable area, so
dismissing the plate can't also open the requests tab;
- `<Show>` is keyed and the label is updated from an effect: `set()`
writes a fresh `RequestData` on every `chat_requests` update, and a
plain `Show` kept the previous count and faces on a visible plate.

Fix stories never opening in production builds
Clicking a story did nothing on the built app while dev was fine — `actions.set`
threw before it could hand the peer to the viewer:
TypeError: Cannot read properties of undefined (reading 'index')
at getNearestStory <- getNearestStories <- checkForNearestSkipped <- set
The logic was right, the bundle was not. `getNearestStory`'s parameter defaults
read `state`, and the minifier bound that read to `ep` — clientPip's module-level
`state`, normally `undefined` — while the body of the very same function kept the
correct name. The source map settles it: minified `ep` maps to store.tsx:133, name
`state`, so one source symbol was emitted under two names. viewer.tsx had it twice
as well, `wasPlaying = !stories.paused` reading `Kd.paused` off a premium-feature
descriptor, so closing any popup resumed a story that was paused.
Both resolve their defaults in the function body now, where the minifier gets the
binding right. rolldown 1.2.3 still miscompiles the old shape, so this is not
something an upgrade fixes.
scripts/check-bundle-mangling.mjs catches the class rather than the pattern, since
the trigger never reproduced in isolation: for every identifier in a default value
— parameter, destructuring, class field — it asks the source map which source
variable it came from and checks how that variable is spelled everywhere else in
the chunk. One dominant spelling plus a stray one is the signature. It finds
exactly these four in the shipped bundle and nothing else, and now runs at the end
of `pnpm build`. It also fails on any U+FFFD, which is how the astral emoji regex
died in the worker chunk.
Vite 8.2.1 comes along: rolldown 1.2.3 no longer rewrites lone surrogates in
folded constants, the trap that one cost us.
`build.cssTarget` is explicit now. `target: 'es2020'` says nothing about browsers,
so lightningcss lowered every logical property into a pair of `:lang()` rules,
emitted after the block they came from and with a higher specificity — a physical
`left` authored next to `inset-inline-*` silently lost, which is what pinned the
emoji panel to the window edge. Naming versions that support logical properties
natively drops 13680 `:lang()` selectors to 1824 and 157 KiB off the CSS. RTL is
unaffected: it runs off `documentElement.dir`, which index.ts sets for every
language.

Fix the expander never collapsing its content
The scoped batch's Completed handler compares _tracker against a value captured
with a post-increment, so the comparison was (n + 1) == n and never held. The
handler is what applies Visibility.Collapsed after the collapse animation, and
PopupRoot.Visibility is set to Visible unconditionally just above it, so
collapsed content stayed visible and kept participating in layout — hidden only
by PopupHost.Height = 0 and the negative margin.
Pre-increment gives the guard its intended meaning: apply the final visibility
unless a newer toggle has started since this batch began.

Both flags are set together on ShareGroupCallPopup, ChatInviteLinkInfoPopup and

it was never part of what is read when the message takes focus.
Both GetSummary overloads share a helper rather than repeating the missed check
that ToOutcomeText and CallContent already make separately.

Start a selection only on a direct hit
ResolvePosition resolves a point to the nearest selectable, clamping when the
pointer is past the end of a line, below the last block or beside a cell. A drag
needs that clamp, but a press was taking it too: pressing on media resolved to a
neighbouring caption, and the capture that follows moved the whole pointer
sequence to the selection root. Nothing else saw it, so a drag out of
PhotoContent never began.
The press now requires ResolvePosition to report a direct hit. Drags still clamp,
so extending a selection past the end of a line is unchanged.
The multi-tap branch tested the same flag to keep gap presses out of the tap
sequence, which the anchor now guarantees.

Allow a selection to start from the bubble surface
Requiring a direct hit kept media drags working but took the gap with it: a press
in the padding beside the text, which ResolvePosition clamps to the nearest
block, no longer began a selection.
The press is now filtered by what it landed on rather than by whether the
position was clamped. Walking up from the pressed element to the root, a
selectable starts a gesture, any other IContent refuses it, and reaching the root
without crossing either means the press was on the bubble itself. Testing the
root by identity would not do: a press on the bubble background reports whichever
template element carries the brush, never the root the manager was attached to.
The multi-tap branch tests the clamp again, since clamped presses can begin a
gesture once more and a click beside the text should not turn the next one into a
word selection.

XAML rejects a FontSize of 0 with E_INVALIDARG. GetOrCreateRun already treats
non-positive as "inherit" and clears the property instead; the fast path now

MessageBubble.Mockup reaches this: it calls SetText without a font size, so the

fast path writing the raw value is the actual defect, so write the resolved one
instead of clearing the property — clearing would inherit the parent's size
rather than applying the theme size.

Fix the expander never collapsing its content (#3329)
The scoped batch's Completed handler compares _tracker against a value captured
with a post-increment, so the comparison was (n + 1) == n and never held. The
handler is what applies Visibility.Collapsed after the collapse animation, and
PopupRoot.Visibility is set to Visible unconditionally just above it, so
collapsed content stayed visible and kept participating in layout — hidden only
by PopupHost.Height = 0 and the negative margin.
Pre-increment gives the guard its intended meaning: apply the final visibility
unless a newer toggle has started since this batch began.

Fix crash when copying an empty selection or an absent note (#3330)
CopyText(XamlRoot, FormattedText) dereferenced its argument immediately, but its
callers pass values that are legitimately null: TextSelectionManager's
GetSelectedText returns null when nothing is selected, BlockQuote passes the
result of FormattedTextBlock.GetSelectedText, and ProfileHeader passes
UserFullInfo.Note, which is null when the contact has no note.
The method is async void, so the NullReferenceException was posted to the
dispatcher and terminated the app instead of being catchable.

Fix the expander never collapsing its content (#3329)
The scoped batch's Completed handler compares _tracker against a value captured
with a post-increment, so the comparison was (n + 1) == n and never held. The
handler is what applies Visibility.Collapsed after the collapse animation, and
PopupRoot.Visibility is set to Visible unconditionally just above it, so
collapsed content stayed visible and kept participating in layout — hidden only
by PopupHost.Height = 0 and the negative margin.
Pre-increment gives the guard its intended meaning: apply the final visibility
unless a newer toggle has started since this batch began.

Fix crash when copying an empty selection or an absent note (#3330)
CopyText(XamlRoot, FormattedText) dereferenced its argument immediately, but its
callers pass values that are legitimately null: TextSelectionManager's
GetSelectedText returns null when nothing is selected, BlockQuote passes the
result of FormattedTextBlock.GetSelectedText, and ProfileHeader passes
UserFullInfo.Note, which is null when the contact has no note.
The method is async void, so the NullReferenceException was posted to the
dispatcher and terminated the app instead of being catchable.
Reported by crash telemetry on 12.9.0.0.

Only log the voip ready state when it changes (#3331)
OnStateUpdated logged before the guard that ignores an unchanged state, so a
source repeating the same state filled the whole log window with identical
lines — one crash report held nothing but Failed, every entry stamped in the
same millisecond, which cost us everything that preceded it.
OnSignalBarsUpdated just below already logs from inside its change guard.
