Steps to reproduce:

After I turned on the Switch Tab in the lab to automatically turn on the picture-in-picture function, I watched the video on the Bilibili website and found that the picture-in-picture window was very small. However, this issue does not occur in Firefox Standard 130.

Actual results:

The actual result you can see my screenshot, which is circled by me with a red line in the screenshot is the picture-in-picture window, which is really small
