UI_DIALOG::event_handler's case `EVENT_WINDOW_CLOSE` can only be hit if `rval == window_event_result::ignored`. Any other result returned before entering the switch. If `rval == ignored`, then returning `ignored` will cause `window_close` to delete the object. Delegate to that deletion instead of having an explicit deletion in this handler.
