This looks like it would spin on the CPU - I don't think it *actually* will
because the faker doesn't post any delayed tasks like a "real" fullscreen would.
i.e. it's guaranteed to only ever loop once. But that means it should be enough
to do something like

EXPECT_TRUE(faker.IsInTransition());
content::RunAllPendingInMessageLoop();
EXPECT_FALSE(faker.IsInTransition());

more below.

You could also do something like faker.FinishTransition(); -- which does
effectively the above code with DCHECKs, and base::RunLoo().RunUntilIdle(); 

(but if that doesn't work, it should use a WindowedNSNotificationObserver rather
than spinning the CPU)

Done.
