You can reverse the chest's opening/closing animation by applying knockback to copper golems

Steps To Reproduce:

1. Place any chests and summon any Copper Golems.

2. Obtain a knockback stick. Following command: /give @s stick[minecraft:enchantments={"knockback":10}]

3. Attack twice on a Copper Golem that is opening the chest.

4. Notice that the chest was forced to close as the Copper Golem was knocked too far away.

5. Wait for the Copper Golem to return and reverse the chest animation.

6. Look the opening/closing animation of the chest has been reversed.
