On the website, going into full screen shifts events in the timeline to the left. Same on the PWA. See below
No fullscreen:

Fullscreen (press Ctrl+.)

I also noted that in full screen, opening the chrome dev tools (press Ctrl+Shift+i) also shifts events in the timeline, but rightwards. Don't know if it can be counted as a bug, though.
