This also happens when someone tries to tame a wolf. I've had an item replaced with 9 bones after a player in my Realm tamed a wolf. The food too, and I've also had a minecart in a hot bar slot get replaced with 23 wheat even when I was not online (I am the owner of the realm though; I don't know if that means my character is always online in the background or something).
