Seems the PR is stuck due to a comment on an orphaned commit... It's a common issue apparently.

Should we perhaps force-merge this? I'm unable to locate the hidden comment through the UI or with gh api graph queries.

@finos-admin Help on this is much appreciated! 😃

@jescalada you could just close this PR and open a new one (rather than reopen this one) with the same branch...
