/**
 * @assertion factory StreamController.broadcast({void onListen(), void onCancel(), bool sync: false})
 * A listener must be subscribed both when the event is initiated (that is, when add is called)
 * and when the event is later delivered, in order to get the event.
 * @description checks that if a listener is not subscribed when the event is initiated,
 * it will not get that event.
