Picture in picture issues

I've been using firefox for a few months now to use ublock origin when watching YouTube. Yesterday I was watching a video and went to open another app on my phone when the PIP stopped playing the video. It appears that the PIP tries to open in full screen (it has the popup stating to drag from top or press back to exit when picture in picture starts) and stops playing. If I go back to the video I can play it normally but essentially picture in picture is not working. I've tried uninstalling and reinstalling, I tried disabling all extensions, I cleared my browsing history, and I searched to see if anyone had a similar issue. Any tips would be appreciated. I've attached a picture of what the picture in picture looks like in case that helps.
