      In SERVER-22760, we allowed certain aggregation pipelines to merge on mongos. However, it seems that the merging logic does not respect the collation when merging sorted results from multiple shards. I can't reproduce this behavior when disabling merging on mongos via internalQueryProhibitMergingOnMongoS.
