Until 2016 Qselect_window was the only event in this group.  And when
Michael fixed Bug#23207 by adding Qfile_notify you said

   Anyway, I think we should simply check all the special events that are
   not user events here.  If they don't have a binding in
   special-event-map, then the test will always fail.

   What about focus-in/out events?  Or xwidget-event?

and we finally ended up with

          && (EQ (XCAR (c), Qselect_window)
              || EQ (XCAR (c), Qfocus_out)
#ifdef HAVE_DBUS
	      || EQ (XCAR (c), Qdbus_event)
#endif
#ifdef USE_FILE_NOTIFY
	      || EQ (XCAR (c), Qfile_notify)
#endif
#ifdef THREADS_ENABLED
	      || EQ (XCAR (c), Qthread_event)
#endif
	      || EQ (XCAR (c), Qconfig_changed_event))

Here we have

(setq while-no-input-ignore-events
      '(focus-in focus-out help-echo iconify-frame
        make-frame-visible selection-request))

so this set and the above are certainly not "in sync".

But I have no idea how these two sets are supposed to interact and
whether and how they should be presented to users.
