The root cause is that in KRaft mode, KafkaYammerMetrics.INSTANCE is configured by KafkaRaftServer [0], which is not executed by the test infrastructure. In contrast, in ZK mode, KafkaYammerMetrics.INSTANCE is configured by KafkaServer [1], so it is in the execution path of the test infrastructure.
