Steps to reproduce

  1. Go to a room with unreads
  2. Click the "Jump to first unread message." ^ up-arrow
  3. Notice that messages are now in a different order and a message that belongs in a thread is shown in the main timeline

Both screenshots are scrolled all the way to the bottom and I've highlighted the visible root message in blue and the other block of messages that gets re-ordered in red.

In the "After" screenshot, the highlighted yellow $YQLdChKbzTkNs94gEGzLzDmTMqBIvd88mmKriKf40xk event should be in the blue thread (not in the main timeline).

Here is another reproduction except there is more messages this time so not everything is in view. But you can see that the red chunk is above the yellow root thread which should be way back in the scrollback. No thread messages showing this time either.

Reproduced the same situation as the comment above again except this time with all of the ScrollPanel and TimelinePanel debug logging in place so the logs should be a lot more insightful around why this is happening 🤞
