I did want to ask mconley about something I noticed as a difference between Picture in Picture versus viewing a video in a tab in the browser

I noticed that, when viewing a video, the background has a semi-gray tone - this is the same when viewing a picture. woul

Would this also be appropriate for Picture in Picture to adopt as a background, rather than white / blank?

Ah, I'm too late :(. They left. I was about to share this bugzilla.mozilla.org/1568373
