WhatsApp Web can't pause videos, and plays them in loop
When I use WhatsApp Web, if I play a video someone sent to me or in a group, I can't pause the video. Besides that, when the playback reaches the end, it starts playing the video again (in loop). It happens both when opening the video (normal mode) and when using picture-in-picture mode. I've already tried to run FF in Troubleshoot Mode, to see if the culprit was any of the extensions I have, but no, the problem persists. I've also tested it in other browsers (e.g. Edge) and the problem didn't occur, so it doesn't seem to be something related to the website.
FF version is 105.0.1 64-bit, running on Windows 11. But I already had the same problem with earlier FF versions and on Windows 10.
