PlaintextProducerSendTest.testSendToPartitionWithFollowerShutdownShouldNotTimeout fails with CONSUMER group protocol

I am getting an error (Consumed 0 records before timeout instead of the expected 100) when running this test with the CONSUMER group protocol.

When I run the test using the CLASSIC group protocol, I can run it 25 times in a row without an error. So it doesn't appear to be flaky (KAFKA-16176). When I run it with the CONSUMER group protocol, it fails 16 out of the 25 runs
