server version: 2.9.3

Minimal reproduce step

I found the similar problem as #14970 and #19692 and #15051 in our 2.9.3 production environment.

It remain offline consumers in consumerList, but it was removed from the consumerSet and consumers. And this subscription become fenced permanently.

But it is different from #19692. The topic of this subscription is not closed, and this topic has other available subscriptions, only 1 subscription remain offline consumers and become fenced permanently.

I have encounter this problem twice. I guess this maybe a new possibility for duplicated consumer problem happen.

Yes. If client restart, it can not consume.
