Is there some dynamic equivalent of document.querySelectorAll("section") JS-based DOM filtering, that listens to websites building new UI elements through dynamic loading and applies the filter on newly added (or modified?) DOM elements (much like how CSS rules automatically cascade when HTML elements are added and removed)?
