the grass block has wrong texture in snowy biome

the grass in the grass block texture normally becomes snow when snow is put on it but when the grass blocks are generated in the "ice plains" , "cold taiga" and "mountains" biomes the grass blocks keep their normal texture and are not snow-covered

it also appeared during snapshots of the 1.13 a little older (18w07a, 18w08a, 18w08b 18w09a ect...)
