Don't recalculate style synchronously on hover/active.
At the end of Document::updateHoverActiveState, we did a synchronous update
of style and layout. That caused a :hover + onmouseover changing a class to
trigger two style recalcs.
There were no obvious reasons why the callers of that method expected the
recalc + layout to happen either.
