TL;DR: I completed a Reopen votes review by myself, as a non-mod, and it seems I was able to do so because my "Leave Closed" vote combined with two others from a previous, invalidated review. Is this intended behavior?
Relevant events from the timeline of the question:
- 18:33:57: Question is closed by five votes (two from a Close votes review).
- 18:33:59: Question is edited and sent for review.
- 19:47: The Reopen votes review (ID# 80035), with two Leave Closed votes, is invalidated, likely because the question was deleted two minutes before.
- 20:30: Question is edited and sent for review.
- 22:19:47: Question is "left closed in review" by the previous two reviewers and I.
- 22:19:48: The Reopen votes review (ID# 80037), with only my Leave Closed vote, is completed.
Later the question was edited, sent for review again, and reopened. There were also various comments, now deleted, and I edited the question outside the queue for grammar a little before voting to Leave Closed. As far as I know none of those should matter.
From When is a review task "completed" or "invalidated"? a review task should leave the queue if:
All review queues
- One moderator action - the moderator's review will be the binding, final outcome
- Post is deleted
- Post is locked (excluding comment-only locks)
- Three "Leave Closed" reviews
- Post gets reopened
- All reopen votes on the question expire
- The question was added to the queue through an edit after being closed, and the user who edited the question later flags it as spam or rude/abusive, and there are no active reopen votes from others cast more than 15 minutes ago.
The first Reopen votes review works fine by these criteria, as it was properly invalidated once the post was deleted. However, the second review fulfilled none of the criteria, unless for 'Three "Leave Closed" reviews' we count the two previous reviews. From the "left closed in review" event it seems this is the case. However that review had a different initiating edit and a different ID#.
Is this behavior intended/expected?
