Recently on EE.SE, a question was edited by its author in a way completely incomprehensible: the whole text was completely removed and a weird non-question was left over. The question in question is here and the edit is here.
The question appeared automatically in the Low Quality Posts review queue. I reviewed it, noticed that it was an old post and probably edited, then rolled the edit back and left a comment for the author.
But before I reviewed the post, someone else did, and didn't notice that - he treated it probably as a new question and voted to close it. And so the question ended up in the Close Votes queue.
This behaviour seems weird to me. When a post is edited and that makes it appear in the Low Quality Posts queue, it should be clearly pointed out that the post was edited. Also, it should be possible to see the revision from the review page, and roll the revision back should be one of the options one has to review.
Now, none of the choices I had really fitted to the situation, so I opened a new tab to rollback the revision, and then clicked 'Looks OK'.
I am aware that this is a very rare case. It will not happen very often that a post automatically ends up in the LQP queue due to an edit, leave alone that the post would actually have been OK before the edit.
However, for those cases, I think it would be good to at least show a notice. Otherwise, people are going to vote to close or delete posts while we could actually do something useful with the post. And if you only show this option when it's relevant (i.e. when the post was edited before getting in the queue), this doesn't make the review layout too complicated.
Disclaimer: I have no clue how often this happens or how much time it will cost to implement the feature I'm requesting.
