DeleteMarker on the target shows `X-Amz-Replication-Status` of `REPLICA`. The status of DeleteMarker replication is returned by `X-Minio-Replication-DeleteMarker-Status` header on `HEAD/GET` calls for the delete marker version in question - i.e with `mc stat --version-id dm-version-id`

It must be noted that if active-active replication is set up with delete marker replication, there is potential for duplicate delete markers to be created if both source and target concurrently set a Delete Marker...
