Description
### Steps to reproduce
1. Open https://matrix.to/#/!QQpfJfZvqxbCfeDgCj:matrix.org/$QWpyPcVtOL6rNdO16dE5E1wZiVPoj5quHfRkMaGMqug?via=matrix.org&via=envs.net&via=beeper.com (TWIM room)
2. Possibly scroll down?
3. Client will hang.
### Outcome
Somehow we have ended up with two timelines that reference each other (each is the other's nextTimeline) so https://github.com/matrix-org/matrix-js-sdk/blob/develop/src/models/event-timeline-set.ts#L967 is looping forever.
