- Go to website with video embed (in my case, ia.net/writer)
- Play video
- Navigate to other tab (gmail)
- Pin the tab
- Close the PiP
- Go to YouTube and play a video
- Navigate back to pinned tab
Upon returning to the pinned tab, the YouTube video will be paused and the PiP of the video from the first website will appear again
I would expect the PiP of the video to not return and the PiP for the YouTube video to enter the PiP player
