Description
This bug is random. I got it twice out of 6 attempts.
Steps to reproduce:
- Have a e2ee room with threads on the last events (the 2 last ones had threads in my case)
- Log out
- Log in
- Verify your device to get access to the key backup
- Open the room
The problem:
The timeline does not show threads for those events.
Notes:
- If I back paginate, other threads are displayed correctly
- Killing the app does not fix the issue
- Clearing the cache fixes the issue
- I cannot reproduce the issue in non e2ee rooms

Research direction
Start with the logout/login, device-verification, and room-opening steps in issue #5716, comparing encrypted rooms with non-encrypted rooms. Check timeline loading before and after back-pagination and cache clearing; done means threads appear for the latest events immediately after login without requiring pagination or clearing the cache.
