> When looking into FLINK-34427 (unrelated), I noticed an odd line in [DefaultSlotStatusSyncer:155|https://github.com/apache/flink/blob/15fe1653acec45d7c7bac17071e9773a4aa690a4/flink-runtime/src/main/java/org/apache/flink/runtime/resourcemanager/slotmanager/DefaultSlotStatusSyncer.java#L155] where we complete a future that should be already completed (because the callback is triggered after the {{requestFuture}} is already completed in some way. Shouldn't we complete the {{returnedFuture}} instead?
> I'm keeping the priority at {{Major}} because it doesn't seem to have been an issue in the past.
