In the Suggested Edits page of the Moderator tools, I noticed that my name appeared in the "approved by" list for an edit I voted to reject. (See image below.)
This seems like a bug, either in that my name should not have been included, or the "approved by" label should be something like "voted on by"
Allowing this might be SE-wide behavior, but starting here in case it's specific to MP&T.
