Severity: medium · Type: bug · Confidence: high

Location: src/app/features/room/PollCreator.tsx:88, src/app/features/room/RoomInput.tsx:1449 and :246-248

Problem

Every other composer action threads correctly (mx.sendMessage(roomId, threadRootId ?? null, …) for text, location, voice, GIF, uploads; sendEvent(roomId, threadRootId ?? null, …) for stickers). PollCreator never receives threadRootId and calls the legacy 3-arg mx.sendEvent(roomId, 'm.poll.start', content), which the SDK resolves to threadId = null (client.js:1784). The poll button is not hidden in threads (only schedule-send is), so a poll started from a thread silently appears in the room's main timeline, orphaned from the discussion.

How to trigger

Open a thread panel → composer poll button → create a poll. It lands in the room timeline, not the thread.

Suggested fix

Pass threadRootId from RoomInput into PollCreator and send with mx.sendEvent(roomId, threadRootId ?? null, 'm.poll.start', content).
