After playing fullscreen video, Firefox seems to maintain the stay-on-top attribute on top Gnome Shell
I'm using 57.0.3 64-bit on Ubuntu 17.10. It seems that when I got out of playing fullscreen video, Firefox seems to maintain the stay-on-top attribute on top Gnome Shell, and Gnome-Shell can't draw notification overlay and dock. Gnome-Shell version is 3.26.2

Are you playing in a fresh start, a tab a new window ? What happens when play in a new window then close it ? What is going on with other part of Firefox ?
Fresh or new tab, and It affects one window only and all tabs on that window. I can create a new window and everything is back to normal
Ok. well i have no idea.

Please let us know if this solved your issue or if need further assistance.
Not necessarily a bug with Firefox and the Firefox build being used is from Ubuntu and not Mozilla anyways.
Unlike with Windows, the Desktop managers on Linux can have the ability to make windows be "Always on top" or such wording.
Have not really used Gnome 3 much to know of its quirks since I am not not a fan of it compared to Gnome 2 (when it was still used) which was much better overall I think.

It seems that I have skipped a detail. The bug only appear if the affected firefox window is maximized. If the window is resized, Gnome Shell can draw notification overlay and dock.

Maybe. What I can tell you is that, I've tried to do this with other applications that can go "fullscreen" such VLC and Totem, and none of them exhibit the same issue. After VLC or Totem exits fullscreen, Gnome Shell can draw over the maximized windows of those apps.
For now, whenever I encounter the issue, I just open a new window, or yank out the tab I want to keep open from the affected window to create a new one, and close the rest
I will consider writing a bug submission
