I recently tried to edit a question and someone else beat me to the punch. I reviewed their edit and felt like my edit would further improve their edit, so I resubmitted my edit. After resubmitting my edit I got the standard message that my edit would have to be reviewed. A minute or so later I refreshed the screen and noticed the "edit must be reviewed" message was gone but someone else was credited with the edit. I thought they must have improved my edit, so I looked at the edit history and didn't see my name.
Either this other user re-edited their edit to match my edit or my edit somehow is under another user's name. To be clear I don't feel the need to have my name on the edit or get the 2 rep from the edit. I just want to understand what happened because it looks like a bug to me.
