In one answer's edit history, Mario and I tried to convert the all caps answer to lower case. It turned out that our edits were exactly the same and were made in the exact same second, but with my edit coming first and Mario's coming second. I remember that Mario's edit history was blank. Then about 3 minutes later, I edited the answer to remove "Simple and quick fix for you hopefully."
However, the edit history incorrectly shows that that that sentence was added to the answer, not removed from it. (The two edit histories for me and Mario were also changed.) I assume it's because the edit was made within 5 minutes so the edit will overwrite the current one, even if it belongs to a different user.
Can you help fix the edit history so it correctly reflects the current version of the answer?
Maybe the system should overwrite edits made within 5 minutes only if the same user as that of the post's last edit made that edit. Otherwise the system should make a new entry in the edit history.
