git push option `merge_request.assign=USER` only works if USER is in the origin repo, not in the target repo.
I have 2 repositories: - upstream - downstream (forked from upstream). If I push a branch to downstream with the following options: `git push downstream new-feature -o merge_request.create -o merge_request.assign=USER` The new merge request will NOT be assigned to USER unless USER is also a known user in downstream. The UI can correctly assign the MR to USER.
