Nightly 71.0a1 (2019-09-17) (64-bit)
Steps to reproduce:
- Launch Nightly
- Go to Amazon Prime and log in
- Play a video from prime video
- Toggle video into PiP window
- Click on "Next Episode" in the browser window
The next episode should be loaded and played back in the PiP window
Video is played back in the main window and PiP window remains frozen with a white frame.
Given that the fix for Amazon Prime toggle availability is not uplifted in Beta, this issue can't be reproduced there.
