Review Comment:
I think we should keep this line, and the we don't need to change the
assertion below (I would expect the only change in this test is to remove the
verify). Should we rename it to `testBackoffAfterFatalError`?

Review Comment:
good question. Actually, if my other
[comment](https://github.com/apache/kafka/pull/18050/files#r1904292495) makes
sense to you all, maybe we don't need to clear the error in the
`AbstractHeartbeatRequestManager`?
We would end up with a simpler alternative where it's the
`coordinatorReqMgr` the sole responsible for maintaining the fatal coordinator
error (sets it when it receives a fatal error, clears it when it receives a
successful response). HBMgr and CommitMgr only read the error to take actions
specific the them, never clear it. Would that work?
