More info can be found in #3534, but as a summary:

The `updateDom` function is not synchronous - there is an undetermined
amount of time between when it completes and when the DOM has actually
been re-rendered and is ready for interaction. The existing notification
(`MODULE_DOM_CREATED`) only fires once on the initial DOM render. This
PR solves the issue of subsequent re-renders by adding a new
notification that fires whenever the DOM is ready after an update. This
notification falls within expected lifecycle notifications (very similar
to other libraries that provide DOM lifecycle notifications).
