Powder snow z-fighting with distant block faces from within

The Bug

The side walls, like those shown in the image, need a significant distance for z-fighting to happen. Perpendicular walls, however, start z-fighting rather early.

Steps to Reproduce

• Summon a large box of powder snow surrounded by blocks.

  /fill ~1 ~ ~1 ~25 ~4 ~25 minecraft:stone
  /fill ~2 ~ ~2 ~24 ~4 ~24 minecraft:powder_snow
  

• Switch into spectator mode, go inside of the powder snow, and look at the walls of the box.
• Take note as to whether or not powder snow z-fights with distant block faces.

Observed Behavior

Powder snow z-fights with distant block faces.

Expected Behavior

Powder snow would not z-fight with distant block faces.
