Issue description

Not much else to say, snow (minecraft:snow) composed of 8 layers does not melt with light.
Biome was set to minecraft:snowy_plains; warm biome melting works for any amount of layers.
The video showcases the issue, sorry that I made it too long, the bug itself is replicated at 0:55
