Item duplication with sending a chest through chunks

Summary: item duplication with sending a chest through chunks

Steps to reproduce:

1. Build a platform at y 13 in the end dimension. Stopping the path at a chunk border or use the test world below
2. Add a chest at the end of the platform using the tool to make sure it's at the edge of the chunk border. Make sure that the chest is floating above the void with no blocks underneath
3. Put a sticky piston and a lever on the piston 1 block away from the chest
4. Place the item you want to dupe in the chest and extend the lever
5. save and quit the game, (wait 3 minutes if on realms)
6. reload the world and retract the piston
7. return to the overworld
8. save and quit again

Observed Results: the chest and the items in the chests gets duplicated

Expected Results: the chests and the items in the chests do not get duplicated
