>             Project: Kafka
>          Issue Type: Bug
>          Components: group-coordinator
>    Affects Versions: 4.0.0, 4.1.0

> When a static member rejoins with a different subscription, we can send the previous assignment to the member in a few cases, such as an unresolved regex or unrevoked partitions.
> Since the subscription has changed, we should act as if the member is new and not reuse the previous assignment.
