Hovered/active/focused nodes will never share style with siblings/cousins.
For any given hovered/active node at a given time, other hovered/active nodes
are either ancestors or descendants of that node. Since style sharing is
looking at siblings and cousins, hovered/active nodes will never share style.
Similarly, there's always a single focused element in a document, hence it
will never share style with another node.
This change bails out early for style sharing in those cases.
