Now, the legacy DOM mutation events are removed. However, DevTools observes the mutations with chrome event synchronously which is similar to DOMNodeRemoved event and the users can modify the DOM while breaking at the removal. So, we cannot back it out even now. Once we'd disallow to modify the DOM while DevTools blocks the running of node removal, we could back that out.
