When my youtube video is set in Theatre mode (press t to toggle), the PiP does not fill the space it is supposed to (please find attached screenshot).
Clarification: This issue is not present when the YouTube tab is set in default view, the issue arises only when YouTube tab is running Theatre Mode.
The PiP should behave the same way regardless of whether my YT is in default mode or theatre mode but in theatre mode there is a glitch.
