Timeline forward-paginates infinitely when jumping to hidden events

### Steps to reproduce

1. Copy the permalink of a hidden event somewhere in the scrollback of a room
2. Click on that permalink

### Outcome

#### What did you expect?

To jump to the area of the hidden event, and stay there

#### What happened instead?

The timeline jumps to the hidden event, and then forward-paginates infinitely as fast as possible, with scroll offset stuck to the bottom. Clicking the 'Jump to bottom' button or another permalink stops this behavior.
