8 snow layers do not suffocate the player

The bug

Standing inside 8 layers of snow does not suffocate the player, even though soul sand has the same hitbox size but does cause suffocation.

How to reproduce

1. Switch into survival mode: /gamemode survival
2. Fill the area surrounding yourself with 8 layers of snow:

   /fill ~1 ~ ~1 ~-1 ~2 ~-1 minecraft:snow[layers=8]

   No suffocation damage is taken

Expected behavior

The player would take suffocation damage when standing inside 8 layers of snow.
