Powder snow can sometimes create z-fighting with blocks placed right behind it in spectator mode

When in spectator mode, sometimes powder snow will z-fight with blocks placed directly adjacent to it.

How to reproduce:

1. Create a void-type world

2. Run the command /fill ~ ~ ~ ~10 ~10 ~10 minecraft:powder_snow

3. A cube of powder snow will be created

4. Place blocks at random positions along the surface of the powder snow

5. Spectate the inside of the powder snow

6. ❌  When moving at least 7-8 blocks away from any wall, the blocks placed there will start to z-fight
