Consider not observing mutations in ns
Content List when it is dirty
Right now nsContentList adds itself as an nsIMutationObserver in ctor and removes in dtor, meaning that even if list is dirty and returns early in mutation observing methods, there are always some virtual calls and state checks. Not observing would mean that mRootNode should probably need to become strong ref.
