I guess I should investigate this

So just to clarify, it looks like the fullscreen icon only goes up over top of the settings during the animation when the controls are showing or hiding. Once it is "stable" with the controls on-screen the view fixes itself.

Also it seems to me that my patch from bug 1432541 fixes this problem. At least I can reproduce the problem without that fix, and I can't any more with that fix applied. So I'm going to mark it as a dependency.

:darkspirit if you could verify on the try build from that bug that it fixes this problem for you as well that would be great. I suspect bug 1432742 and bug 1431326 might be in the same boat but I'm having a harder time reproducing those reliably so it's hard to say.
