Likely reproduction steps:
- Revision R has multiple package reviewers, owned by users A and B, both of whom are non-authors.
- Open a window as user A and prepare to accept.
- Open a window as user B and prepare to accept.
- Submit window A.
- Submit window B.
Expected: goes through cleanly.
Actual: Dialog with error: Reviewer "PHID-OPKG-xxx" is not a valid reviewer which you have authority to accept on behalf of.
