This maybe related to ~~FLINK-34624~~ as we could see from the log:

03:31:02,073 [ main] INFO org.apache.flink.runtime.testutils.PseudoRandomValueSelector [] - Randomly selected true for state.changelog.enabled
03:31:02,163 [jobmanager-io-thread-2] INFO org.apache.flink.state.changelog.AbstractChangelogStateBackend [] - ChangelogStateBackend is used, delegating EmbeddedRocksDBStateBackend.

~~FLINK-34624~~ disables changelog since it doesn't support local rescaling currently.

Even if disabling changelog for AutoRescalingITCase manually,
randomization may still be applied to it.
We should apply randomization only when it's not pre-defined.
