Player takes magma damage from the block above when swimming if the magma blocks are placed in a specific way

In a one block space when swimming against the ceiling, the player can take magma damage through the block above the player's head. I am not using any mods in the video, just an animation texture pack.

Steps to Reproduce:

1. Build the pictured setup:

1. Switch to Survival mode

2. Swim inside the one block space and hold the Jump key

Observed Results:

The player takes damage from the magma blocks. If you remove the magma blocks on the side, the player no longer takes damage.

Expected Results:

The player should not take damage.
