Placed after the last item a list shows, it asks for more as soon as it comes into view, and stands in the list
meanwhile as a turning mark saying that more is on its way. A list with nothing left to fetch stops rendering it.
A trigger still in view once the batch it asked for has landed asks again as soon as it is handed a new onLoad,
so a batch too short to push it out of view is followed by the next one without the reader having to scroll.
The mark is decorative: waiting is for the list the trigger closes to state, for instance through aria-busy.
Creates an incremental loading trigger.
