Burning mobs are extinguished by snow in cold biomes, but not in snowy biomes

The bug

Burning mobs are not extinguished by snow in snowy biomes. However, they are extinguished by snow in cold biomes where the snow starts at a certain height.

This also happens with medium biomes with the snow above y = 256.

How to reproduce

1. Create a Buffet world with biome "Snowy Taiga" (for example, you can choose any snowy biome)
2. Run /weather rain
3. Spawn a zombie when it's day or use

   /summon zombie ~ ~ ~ {Fire:1000s}
   

   → It won't get extinguished by the snow

4. Repeat the process with a "Taiga" Buffet world above y = 140
   → The zombie will get extinguished by the snow
