Fix broken viewport percentage length units after a viewport resize.

Browse source 
When a viewport is resized, the computed values for a style containing viewport percentage length units become stale. However, there's no way for those styles to be invalidated after a resize. As a solution, this commit invalidates the computed values cache after a resize has occurred, which is probably over-kill.

A better solution would probably be to track under what conditions computed values remain valid, and invalidate them as indicated.
