fix(event-loop): flush UI when no input is available (#25728)

Problem:  With lots of events, UI flush may be delayed for too long.
Solution: Flush UI when no input is available. This still flushes less
          frequently than before #25629, when a flush also happens when
          typeahead buffer is empty but input is available.
