I don't think this is true. I think you just need a way to force style calculate both before and after. I think that a call to getComputedStyle both before and after would do the trick.

Let me know if I should make this test more extensive. It currently tests :only-child, and not first/last/nth. However, that should be enough given what this test is trying to prevent.

This test was used to catch a situation where a RenderStyle is cloned and reapply without copying the RenderStyle's state information, which used for pseudo class styling.

Good idea. It makes the test clearer as well.
