<!-- The test checks that composited layers are created when needed to display elements in front of animated layers.
There are two animations going at the same time. The second animation is inside a clipping
container (white background with black border). The first animation should display behind the clipping container.
For both animations, the following should be true:
1. Yellow box should display in front of the blue box.
2. Gray boxes should display behind the blue box.
