Minor bug, but apparently a user was able to submit an edit suggestion on my answer after I deleted it. I tried to handle it from the answer's edit link, and the system didn't let me – I got a popover error message saying that edit suggestions on deleted posts could not be reviewed. However, I was able to review it by following the review link on the notification I got for that edit. Also, another user had already reviewed it before me.
I'm not sure what's wrong here, but I believe the system should not have allowed the edit suggestion to be submitted in the first place. And, after it was, it should have prevented me and others from reviewing it.
As I said, it looks like a minor bug, as it's about a deleted answer. I'm just posting this for the record.
