> it can be reproduced by GroupAuthorizerIntegrationTest.testConsumeUnsubscribeWithoutGroupPermission.
> The root cause is shown below.
> 1. AsyncConsumer#unsubscribe is executed
> 2. process(UnsubscribeEvent) changes the state to LEAVING
> 3. the state is changed to UNSUBSCRIBED in generating Heartbeat
> 4. the `LeaveInProgress` is skipped in transitionToFatal since the state is UNSUBSCRIBED
> The behavior is inconsistent to classic consumer
