UID/GID not restored for Objects Stored in Glacier

I don't believe this has anything to do with the object being stored in Glacier. I just uploaded the same file to S3 standard and then downloaded via a threaded download. Here's how to reproduce with a file above the multi-thread-cutoff threshold.

  1. Upload
# rclone --config /root/rcs3/POC/config/rclone.conf --s3-shared-credentials-file /root/rcs3/POC/config/credentials --metadata --links --transfers 2 --checkers 32 --progress --include pero.scaff.fa.pac copy /pub/ppapadop/testdir s3-backup:testing
Transferred:      590.125 MiB / 590.125 MiB, 100%, 45.393 MiB/s, ETA 0s
Transferred:            1 / 1, 100%
Elapsed time:        13.3s
  1. Checking metadata on S3, Object is stored in standard. Other metadata is correct
# rclone --config /root/rcs3/POC/config/rclone.conf --s3-shared-credentials-file /root/rcs3/POC/config/credentials --metadata --links --transfers 2 --checkers 32 lsf --format "ptTM" s3-backup:testing
pero.scaff.fa.pac;2019-04-05 12:37:55;STANDARD;{"atime":"2023-06-09T11:34:03-07:00","btime":"2023-11-15T16:34:30Z","content-type":"application/octet-stream","gid":"1698224","mode":"100644","mtime":"2019-04-05T12:37:55-07:00","tier":"STANDARD","uid":"1698224"}
  1. Downloading file without multi-part-cutoff specified
# rclone --config /root/rcs3/POC/config/rclone.conf --s3-shared-credentials-file /root/rcs3/POC/config/credentials --metadata --links --transfers 2 --checkers 32  --include pero.scaff.fa.pac  copy s3-backup:testing /tmp/ppapadop
  1. checking ownership (incorrect), should be ppapadop:ppapadop
# ls -l /tmp/ppapadop
total 604292
-rw-r--r-- 1 root root 618791129 Apr  5  2019 pero.scaff.fa.pac
drwxr-xr-x 2 root root        56 Nov 15 08:06 testdir
  1. Redoing by erasing local copy, downloading with the --multi-thread-cutoff 1024Mi and things are now correct
# rm /tmp/ppapadop/pero.scaff.fa.pac 
rm: remove regular file '/tmp/ppapadop/pero.scaff.fa.pac'? y
# rclone --config /root/rcs3/POC/config/rclone.conf --s3-shared-credentials-file /root/rcs3/POC/config/credentials --metadata --links --transfers 2 --checkers 32 --multi-thread-cutoff 1024Mi --progress --include pero.scaff.fa.pac  copy s3-backup:testing /tmp/ppapadop
