Export issue: Comments on commits that are not part of PR are not getting exported

[Ana Stankovic]

I am using the below command to export my project:

curl -u myadminuser -s -n -X POST -H 'Content-type: application/json' -d '{"repositoriesRequest":{"includes":[{"projectKey":"*","slug":"*"}]}}' http://localhost:7990/rest/api/1.0/migration/exports | jq .

When I look into files that I get as a result of the export, I cannot find comments that are left on a single commit outside of PR. However, I do see comments that are left within the PR discussion.
Is this expected, or is there anything I can do to get these comments exported?
