SuspenseList in DevTools could cycle through the Suspense states

We currently have a way to force a fallback on a Suspense boundary in DevTools. It might be cool to have a "play" button or something on SuspenseList that cycles through the states. E.g. if it's "together" mode it shows all the fallbacks and then switches to showing all the content and then back again in a loop. If it's "forwards" it shows all the fallbacks then one at a time and then back to all fallbacks. If it's tail "hidden" or "collapsed" it hides all the ones that are not yet inserted and then inserts one at a time. Could be a nice way to demo/test the loading sequence experience.
