We need to be careful as to how much we want to respect this attribute.
V1 apps are maximzed instead of put in fullscreen when the user presses the
fullscreen button on the keyboard. A v1 app can still be fullscreened though.
(Chrome remote desktop is a v1 app which most definately can be fullscreened)

Separately I am working on making it possible to put v1 and v2 apps into
immersive fullscreen. I want to have a flag in chrome://flags to do this by the
end of next week.

oshima@, can we further discuss your plans wrt to fullscreen. This is a
fullscreen related CL which will be landing on Friday (today)
