Description Karsten Thoms

This is a follow-up of bug#562127.

With the previous change the style computation in getComputedStyle() got improved. For this a node's hierarchy is computed which gets passed into the selector matching.

The hierarchy is computed on an element's parent, if present. Due to the fact that several nodes share the same parent, the hierarchy for the parent node will be the same. This makes it a caching candidate.
