What if these DOM nodes could use a special class of observers / listeners that automatically set themselves aside when the node is deleted from the document, and re-instate themselves if the node is re-inserted in the document? Similarly for when the window goes away.
Instead of addObserver or addMessageListener, you'd have observeWhileInserted or listenWhileInserted. Implemented in some clever and efficient way to avoid thrashing during heavy DOM manipulation.
