We need to prevent these mutation observers from being garbage collected, and since they are only part of SimilarOriginWindowAgent and themselves as part of the intrusive list, nobody is visiting them. Make the list of pending mutation observers a GC::RootVector so we keep them alive until they have been processed in the microtask. Restores 1400+ WPT subtest passes in `dom/nodes/Element-classlist.html`.
