By design, the {{core_node24_recovering}} and {{core_node24}} should be always
equals to each other. The reason here is {{ZkShardTerms.ensureTermsIsHigher}}
also increase the {{core_node24_recovering}} is a higher number. This will lead
to a case when a replica finished recovering but it won't be able to become
active.
