[Twizzle issue] Player always jumps to the beginning of move sequence in Firefox

[hundertzwoelf]

Steps to reproduce the issue

1. Open Firefox
2. Go to alpha.twizzle.net/edit
3. Enter moves

Observed behaviour

When entering a move sequence, the player does not stay at the end of the sequence, instead it always jumps to the very beginning. When I press the the forward button, it shows the resulting state, but jumps to the beginning again after entering new moves.

This issue is not happening on Chrome/Chromium, and I can reproduce it on Android (using Firefox and Chrome) as well.

This is also not happening on alg.cubing.net, which is what I fallback to to do reconstructions.

Browser & operating system

Hmm, I can also reproduce on Firefox.

This kind of thing might be really easy to fix or really hard. It's a bit hard to tell until I dig into it.
