In reference to this post, I received two notifications that my post was edit, but there was only one edit in the revision history. However, there was a noticeable difference in the notifications, that the title had been changed (old on bottom, new on top).
So why did I get notified twice that my answer was edited? My answer was clearly edited only once, yet it seems that I got a second notification indicating the question was also edited, but the notification doesn't actually say the question itself was edited? Is there some sort of bug that duplicates the notification if the question and answer are both edited close together?
