Attachment: blockAutoplayLinuxBug.mp4

Mozilla/5.0 (X11; Linux x86_64; rv:63.0) Gecko/20100101 Firefox/63.0 ID:20180726100339

STR:
1/ Go to https://www.dailymotion.com/video/x7op91
2/ Wait for the doorhanger dialog to pop up to block/allow autoplay
3/ Switch to another application with your keyboard or the mouse

ER:
The Firefox window goes to the background

AR:
The Firefox winfow goes to the background but the doorhanger menu remains on top of the other application

I am attaching a small screencast showing the problem.

This is on Linux (Ubuntu 18.04), I can't reproduce in a Windows 10 VM
