The bug was a little unusual but it can't hurt to relnote. Release Note Request (optional, but appreciated) [Why is this notable]: When viewing multiple PIP windows, making one fullscreen would put the Windows taskbar in front of it. There may also have been other fullscreen cases that got the taskbar. [Affects Firefox for Android]: No [Suggested wording]: An issue where the Windows taskbar would appear in front of fullscreened PIP windows has been fixed. [Links (documentation, blog post, etc)]: None
