River biomes that run through mountains don't have snow at high altitudes
Unlike in the taiga biomes, which have frozen river biomes, normal river biomes that run through mountains don't have snow in higher altitudes. This leads to strange patches of rain amidst snow storms.

Affects 1.20.1 Release Candidate 1

Interesting, although that would require generation changes, and the frozen river biome would apply to the entire area vertically. It'd work better to apply cold the same way to it, to freeze it.
It's not a bug, just a wrong way to code Mojang used.
Minecraft checks at first terrain generation which blocks are over 90. The complete Y-axis of these blocks will have snow on. It's not because you make a pillar to Y90 that it'll snow on (yes I know it works in a weird way).
