This question already has an answer here:
The review system flagged me down in an audit for trying to edit a vandalizing edit. The vandalism was trivially undoable (two clicks and delete), and I had an edit in mind anyway - so I was trying to do it quicker without opening the question on another page. I think the review system should only act when your action is finished. In case of an edit, clicking "Edit" doesn't mean you actually did anything just yet!
Shouldn't this misbehavior of the review system be considered a bug, and shouldn't it be fixed?
