1. in Talk in the browser (Firefox 129.0), open a Talk recording (webm)
2. Click on fullscreen button
3. it goes to fullscreen for the blink of an eye
4. goes back to normal view

Expected behavior
fullscreen mode works

can't check viewer version

Edit
there is also this other fullscreen view that you can toggle in the top right ...-menu in the Talk window. Then the video is still not fullscreen, but bigger than before. But there are also problems with this view (should I open a separate issue for this?):

• title of video overlapping the icons at the top
• top right controls are overlapping and cannot be used properly

@skjnldsv I can reproduce on c.nc.com on NC30.0.0
(both ways of doing fullscreen, as described above, don't work properly)

can you remove "needs triage"?

This is fixed in 30.0.1 (cloud.nextcloud.com)

Feel free to reopen if anyone experiences this for lower versions
