I found this now deleted question in first-posts review. Somehow @MARKDOWN was able to edit the question after it was deleted:
How is this possible?
You reviewed this question in the 'first posts' review queue, shortly after which, it got deleted.
However, before it was deleted, an edit was suggested. This placed it in the edit queue.
Now, a question can still be edited after it's deleted (with the right privileges), so the question stays in the 'suggested edit' queue, even though it has already been deleted.
In this case, the edit got approved after the question got deleted, although the edit was suggested before the question got deleted.
