I was looking at the suggested edits for a post and I did not think that the changes proposed were encompassing enough to warrant a modification to the post, so I rejected it. After rereading the suggested edit, however, I realized that the edit was valid and I wanted to change my flag to "approve" instead. I saw no option to do so.
Do edits behave like votes in that I am able to alter them for a few seconds after I make my original judgement or are they concrete and there are no options to modify an edit approval/rejection once it's been set?
