Describe the bug
The animation is applied to another player but not to me (it works the other way around) (works only if player is on my screen). Through trial and error, I realized that the culprit was the MCA Reborn mod—after I removed it, the issue disappeared.

To Reproduce
Steps to reproduce the behavior:

1. Install MCA Reborn mod.
   

2. Launch Minecraft.
   

3. Connect to multiplayer world.
   

4. During character creation:
        - Set the first player’s model to "Player".
        - Set the second player’s model to "Vanilla". (This might not even be necessary, but that's how I reproduced the issue)
   

5. Open the survival inventory (where player model are visible).
   

6. Attempt to:
        - Punch the air.
        - Place blocks.
        - Sneak.
   

7. The issue should now occur.
