Reproduces on Windows 10 (other platforms not tested), on both 82 Release and 85 Nightly.


  1. Ensure Side View is installed. This was a 2018 test pilot experiment.
  2. Go to a video site, in my case.
  3. Click the "Open Side View" extension icon.
  4. Select the site from step 2.
  5. In the side view, play a video.
  6. Click the PiP button on the playing video. You might have to widen the side view so it shows.

Expected: Video stops playing in side view, starts playing in PiP window.
Actual: Video continues playing in side view, PiP window opens but is solid white.

Expected: Clicking the X to close the PiP window closes it.
Actual: Clicking the X in the PiP window does nothing.

At least one can close the PiP window by alt+tab and then clicking the X there. Other platform methods probably apply.
