  const domBodyObserver = new MutationObserver(() => {
    // We expect the body node to be stable once parsed / created
    if (document.body != null) {

      handleExistingNodes((document.body: HTMLElement));

      // We can call disconnect without takeRecord here,
      // since we only expect a single document.body
      domBodyObserver.disconnect();
