Hey jackyzy823,
Thanks a lot for reporting this bug! I couldn't reproduce it on Firefox 124.2.0, can you still reproduce it? 

If yes, could you please attach a video?

I was able to reproduce the issue as of 20240402. (and i actually have a screen record at that time being)

But i couldn't reproduce today :( maybe site issue?

I could reproduce it now, following your step by step video, thanks.

One more symptom I can see is, when showing the tabs tray from the Channel page (after hitting back from the Video page), if the "Play button" is visible, I can hit him, and the video will play. It shouldn't, as I am now on the Channel page.
