I think you should try to filter the extra events in your own code by e.g.
ignoring any of them pertaining to the item you're already trying to return
selection to.

There is probably a bug but I'd say that the wrong thing to do is to try
to emulate vetoing a selection event -- it's not possible for a good reason
and your users wouldn't expect it.
