Summary:

Player hitbox is clipping through stackable entities when jumping on it. On game reload, they don't.

Impact:

It's less than ideal that a player gets hurt while jumping on the boxes in Lava Town. 

Repro Steps:

1. Download "Rescue Mission: Lava Town" from the marketplace
2. Teleport to -278 63 154
3. punch a box into the lava
4. jump on the box
5. leave the game
6. open the game
7. jump on the box again

Observed Results:

When the player jumps on the box before they leave the game, they get set on fire. This did not happen in 1.12 and earlier versions. When they leave the game and return, and jump on the same box, they do not get set on fire.

Expected Results:

They should not get set on fire at all, as their hitbox should be above the lava as it was in 1.12 and earlier versions.

1.12.1.1 and all 1.12
