Mark the outmost dirty style containment scope only if it has changed

During the creation of the style containment scope the ancestors are created on the fly and are marked as outmost dirty in such cases. But that's not correct as if nothing is changed in the new ancestor, we don't need to update the outmost dirty scope. Dirtying parent style containment scopes outside a size query container during layout leads to modifying the layout box tree outside the query container which is not allowed.
