webanimations/partly-accelerated-transition-by-removing-property.html [ Failure ]

The test fails cause the expectation is empty: it's a dump of the layer tree and there are no layers. But on WPE there are layers. This is the diff

I suspect this is just because WPE is always in accelerated compositing mode, and the test expects that removing the animation will cause webkit to leave AC mode. I'll check this and update the expectations if that's the case.
