----------------------------------------------------------------
The issue is caused by the alignment of desired and sufficient resources
definition in FLINK-36014. The desired resources is still calculated based on
the free slots (which makes sense for {{WaitingForResources}} state but not
{{Executing}} (because slots are still allocated while the job is running).
The open question is why this wasn't revealed by the
{{RescaleOnCheckpointITCase}} within [FLINK-36014
PR|https://github.com/apache/flink/pull/25307] CI run. This seems to be a
consistent issue for this test.
