A merge request is supposed to be automatically closed when the commit(s) to be merged are pushed to the target branch (whether directly or in a merge). If the commits to be merged are instead cherry-picked in (on top of another commit so that their SHA changes), they get a different SHA, and so the merge requests are not automatically closed.
### Proposal
- if cherry picked through the GitLab UI, close the merge request as merged
- if cherry picked through the command line ... TBD
