Comment 1 for bug 1665723

Same problem occurs, after exiting child window fullscreen:
- Launcher set to always show
1) open youtube.com
2) maximize browser window
3) play a video, and press the fullscreen button
4) press esc, F11 or click the fullscreen button in bottom right to exit fullscreen
5) Expected result: parent window is still maximized and not obscured by launcher. Actual result: parent window maximized but obscured by launcher
