The media gallery and activity log register filtered timeline sets on the room (getOrCreateFilteredTimelineSet); the room re-emits their events as live RoomEvent.Timeline, so every matching event reached "new event in the room" listeners twice for the rest of the session. The timeline window shifted by an extra message per event (loaded messages vanished), and notifications, unread counts, widget feeds and ring handling saw duplicates. isFromFilteredTimelineSet() (unit-tested) identifies emits from a filtered set; the room timeline, roomToUnread, message notifications, clock-skew sampling, call ring/decline handling and widget event feeds ignore them. Verified headless (40 messages, every 5th a file; gallery opened; Bob sends 3 files + 1 text): before, the first rendered message drifted from the room start to "file15"; now it stays put.
