Before this change, removing a style element from inside a shadow tree would cause it to be unregistered with the document-level list of sheets instead of the shadow-root-level list. This would eventually lead to a verification failure if someone tried to update the text contents of that style element, since it was still in the shadow-root-level list, but now with a null owner element.
