Pressing F11 should toggle the application level fullscreen.
Note that this is different from page level fullscreen, which is triggered by the page itself.

We should research if we want to merge the two concepts so that for the user there is only one notion of fullscreen and only one way to exit fullscreen, regardless of how it was activated (F11 or page interaction).

Or if we want to have to have one way to escape app level fullscreen (e.g. F11) and one to escape page level fullscren (e.g. ESC)
