Looks like these only fail on WPT.fyi, not in our infrastructure.
Looks like very very subtle differences due to float/double precision when combining multiple transforms.

We could potentially use float precision instead of double, which would hopefully cause these to end up identical.
Alternatively, we could use precomputed sin/cos values for 'common' degree values.
We could also just fuzz the tests (more), since the rendering is visually identical.
