/**
 * @assertion bool isPaused
 * Whether the subscription would need to buffer events.
 * This is the case if the controller's stream has a listener and it is paused,
 * or if it has not received a listener yet. In that case, the controller is
 * considered paused as well.
 * A broadcast stream controller is never considered paused.
 *
 * @description Checks that if the controller's stream has not received a
 * listener yet, isPaused returns true.
