1113559 - [e10s] youtube video overlay from other pages when playing HTML5 video fullscreen

Attachment: Screenshot of the fullscreen bug

Page that gave me the error, haven't tested with others
(http://studentski.hr/vijesti/kultura/video-najgore-pjesme-u-2014-godini/)

When playing a youtube video fullscreen in any other tab, I can see and interact with videos from the tab above. After leaving fullscreen, overlays are persistent and don't go away. Only solution is to shut down FF.

For me, pressing the fullscreen button for the videos on http://studentski.hr/vijesti/kultura/video-najgore-pjesme-u-2014-godini/ does nothing.

I can confirm that Paul Silaghi.
It didn't (nor it does) work for me too.

To see the problem:
1. open that page in one tab
2. click on youtube icon in any of the videos on the page to open a new tab with that song on Youtube
3. whilst on youtube.com press icon for fullscreen
4. then you'll see the overlay problem

Depends on the bug 1095754
This also possibly a duplicate of the bug 1106243

Paul are you still able to reproduce? I'm not able to using the following steps:

1. open the following page and scroll down until you see the an embedded video (windowed flash)
http://studentski.hr/vijesti/kultura/video-najgore-pjesme-u-2014-godini/
2. click on a youtube icon in any of the videos on the page to open a new tab with that song on Youtube
3. whilst on youtube.com press icon for fullscreen
4. approve the full screen request

no overlay problem here. Testing on win7 with nightly, e10s enabled.

I can no longer reproduce the problem on 38.0a1 (2015-02-05) Win 7.
Instead I see a rendering issue when scrolling the page with the embedded videos: http://i.imgur.com/Q4lE3co.png
What do you think, Jim ?
