Attachment: Marionette test of the fullscreen API, to be run against B2G emulator to illustrate issue

document.mozFullScreenEnabled is set to true in the context of Marionette content. However, calling document.documentElement.requestFullScreen() fails and results in a mozfullscreenerror event. My understanding from the docs is that the former attribute should be a reliable indicator of whether the request would succeed.

I've attached a short Marionette test illustrating this, along with its output. It can be ran against a checked-out mozilla-central repo as follows:

python ~/mozilla-central/testing/marionette/client/marionette/runtests.py --emulator arm --homedir <PATH-TO-B2G-ARM-EMULATOR> ./test_fullscreen.js

jgriffin can fix you up with an emulator if you need one; drop him a line directly.

This may intersect (or duplicate) Bug 684620. After a short discussion with jgriffin, have filed separately since Bug 684620 is specific to multiprocess.
