@Aslam97 thanks for this, but I don't think this is the direction of where we want to go in exposing this configuration. For one, this should be known upfront, so the useEffect feels like a hack, than a supported solution.

Secondly, I don't know that it is worth it to switch between which API to use just for this. Instead of listening to the root level element this should switch to the editor dom element instead & listen on that, so no need for handleDOMEvents api which does essentially the same thing as an addEventListener would
