nit: Can you add a comment for this test explaining how browser fullscreen is
different from tab fullscreen?

E.g.
// Prevent inline install while in browser fullscreen mode. Browser fullscreen
// is entered by the user by pressing F11.

(and same for the next test case)

Done.

You probably don't need this since the dialog won't open in the first place?

[Devlin, 2016/10/10 18:35:59]

I think I suggested this when Ben was talking to me about it.  I wanted to make
sure that everything *would* succeed if the error wasn't thrown.  Without this
check, there could be a silent test failure where the extension doesn't get
installed, but the reason it doesn't is because we stall at the dialog showing -
when in fact the dialog should never be shown.

It's probably a little superfluous with the error checks in the js, but it makes
me feel a bit better.

[Ackerman, 2016/10/10 19:35:58]

Keeping per Devlin's comments.

Okay, sounds good. I guess without it the test would timeout instead of failing.

Also not needed?

Same comment as above.
