Most of the time when styles need to be recreated, the name and classes of the css node haven't changed. In this case, the change value will not change either, since we are computing change under the assumption that name and classes are unchanged. So don't recompute the change. This avoids the second match we do to find the superset, cutting down the number of times we consult the selector tree.
