alancutter@ -- are these tests (this and the one below marked as removed)
actually aiming to test composited behavior? I want to make sure they aren't
just passing now due to being de-composited even when compositing feature is
enabled if their purpose is explicitly to make sure they do composite when
feature is enabled. If that makes sense.

[alancutter (OOO until 2018), 2017/03/21 00:32:12]

Thanks for the prompt. Looks like this test does depend on running on the
compositor for the purpose of synchronising with CC. I suspect changing
waitForCompositor() to box.animate({transform: ['scale(0.5)', 'scale(0.5)']})
should get it composited again though the expectations will need rebaselining.

The other timeout expectation removals look fine to me.

I double checked this and it is creating a compositor animation as-is in SPv2,
so we're good. I'm not sure why I thought it wasn't.
