Donkey/Mule/Horse Item Duplication

Donkey/Mule/Horse Duplicate their items upon death

If one of the following has saddle, armor,or items on a chest. Upon their death, their items will be duplicated.

I discovered this in my survival world when my donkey was blown up by a creeper. The items in his chest was duplicated. Immediately opened a creative world a tried to duplicated the bug. I spawn a donkey, tamed it put oned a chest and placed items. I then blown it up. Its items was duplicated. To my surprise, it also works on the other two. The horse also duplicated its armor and saddle upon death. I also found out that just needs to be killed (not Blown up) to make it work. I killed a horse and its items was duplicated

I don't really know if anyone have reported this but I don't really want this bug to be abused
