I recently flagged some positively-scored answers that weren't answers by our local policy for that kind of question.
All reviews are completed by now, but regardless of the reviewers' votes, nothing has happened.
This review, for instance, had the unanimous decision to delete the answer. My flag was marked as helpful, but the answer was not deleted.
This is not a duplicate of this question because there the answerer undeleted the answer after it was deleted from review. This has not happened here, the answer was never deleted.
Since I couldn't find anything else stating that this is intended behaviour, I believe this is a bug.
Or, if this is intended behaviour, what's the point of sending answers with positive score into the LQ review at all?
