Duplication possible with Donkeys, Llamas, and Mules.

Hello, I have heard of this duplication glitch that involves Donkeys, Llamas, and Mules. I am concerned of how this can affect progression on survival servers. The glitch requires two players and can be replicated by doing the following:

1. Gain a tamed Donkey, Llama, or Mule.
2. Equip the animal with a Chest.
3. Place items you wish to dupe in the chest.
4. One player (Player 1) must then sit on the Animal and leave the game.
5. While Player 1 has left the game Player 2 must take the items from the chest.
6. Then Player 1 joins back and duped items should appear in the Chest.
