I don't really consider this to be the answer to the question, but I'd like to share it anyways because it's better than nothing.

This question has some good answers: What is the most efficient way of detecting when an element with a particular ID is inserted in the DOM

In particular, this answer: https://stackoverflow.com/a/25107064/4808079 from schettino72

iframe elements trigger load/unoad events. You can insert a dumb iframe in the element you want to watch... And trigger a 'load' event in the original element yourself.

functionwatch($ele){
    var$iframe = document.createElement('iframe');
    $iframe.style.display = 'none';
    $ele.appendChild($iframe);
    $iframe.addEventListener('load', function(){
      var event = new CustomEvent('load');
      $ele.dispatchEvent(event);
    });
}

I would still like to keep this question open as this is a hack and not a true answer. DOMNodeInserted was probably not deprecated so everyone could do it this way instead.
