I've heard on the chat, that a post gets out of the review queue if a 3k+ user edits it as part of the review. More details can be found here. It may be an unintended side-effect, or a non-trivial interpretation of the spirit of the review votes from the software development side of the SE engine.
What happens if a 3k+ user makes this edit out of the review queue? (I.e. right click on the post title, opening it in a new tab and doing the edit in it?) Does this side-effect happen also in this case?
