optional nit: These could go on one line.

It might be clearer to call this at the beginning of the ImmersiveFullscreen
test below, so you wouldn't have to explain in NonImmersiveFullscreen why the
setting doesn't affect the test.

We would need to call for
ImmersiveFullscreenConfiguration::DisableImmersiveFullscreenForTest() in
ZoomBubbleBrowserTest.NonImmersiveFullscreen.
I think the comment about tab fullscreen is still valuable. Otherwise, someone
may think that we can ifdef out ZoomBubbleBrowserTest.NonImmersiveFullscreen for
CrOS.
