This is really a kind of special case. You could add a pad-probe on
output-selector sink-pad and ref the tag-event. Then you can resend it
whenever switching pads. It might be a good idea to actualy add this to
output-selector (add a "resend-tags" property, that is by-.default off.
Could you file a bug for it? Should not be difficult to be added.
