 * A host page can remove the container a React app renders into without calling `root.unmount()`, such as a Backbone view's `.remove()` or a router that caches a route's DOM. The app's cleanup then never runs, so watching the element is the only way to notice.
 *
 * Moving an element is not leaving: removing and re-adding it in the same task reads as still connected, because observers report after the task ends. The roots are read again on every report, so an element moved into a different shadow root is still watched.
