When snowy taiga trees are generating in a snowy taiga biome, the whole tree should be covered in snow.
However, as of right now, the snowy taiga trees will lose all of the snow off of the leaves that generate in a different chunk.
(the snow on snowy taiga trees breaks when generating on chunk borders)
(This bug was still present in 1.20.1)
