When reviewing the queue of suggested edits, I did the inevitable and thought to myself: "Improve!", but accidentally clicked "Approve" (perhaps related to not being a native English speaker).
As I clicked I immediately felt I clicked the wrong button, but I couldn't find any mechanism to revoke my action (or rather, change it and actually "Improve" the edit). If I try to edit the post in question which still has a pending user edit, instead of an edit box I get the message
You have already reviewed this item.
and no opportunity to take any action.
Is there some reasoning behind not being able to revoke the action, or is it just unimplemented for the time being (or am I just bad at finding the function)? I feel that the review history list would be the obvious place.
The edit in question, if it is relevant.
