I was going to say we should wire up exiting full screen, but then I remembered
that we don't show the ui in full screen... :)

Also, isn't fullscreen automatically exited when you navigate?

[amp, 2017/05/09 16:38:07]

Yes it should be, although I'm not sure where that is wired up.

The main concern was if we are not doing what the user expected.  If the user
pressed back and expected to get back to the page where they started the full
screen, then navigating to the page previous to that would be bad.  That's why
we had the check in there before, to just exit fullscreen instead of navigating
away.

Since we will no longer have navigation ability in VR fullscreen anymore that
shouldn't be an issue.
