Instead of trying to locate the relevant StyleSheetList on style element removal from the DOM, we now simply keep a pointer to the list instead. This fixes an issue where using attachShadow() on an element that had a declarative shadow DOM would cause any style elements present to use the wrong StyleSheetList when removing themselves from the tree.
