I could make things go awry with this patch.
start playing a video (not YouTube), go to full screen. Now put the video in PiP and press the X button in the top right corner.
The video would exit PiP mode and go back to non-full screen but the video has now disappeared. Tapping play can only allow you to hear the video, but you can't see anything

The Windows bot failure is unrelated, only iOS code is changed by this patch.
