It is not a duplicate. That wasn't a microbiome. The frozen river was several hundreds of blocks long.
Why is this marked as a duplicate? It clearly isn't.
Not a duplicate.
Can confirm, please reopen.
Can confirm for 1.19.1-pre4
Can confirm for 1.20 and 1.20.1 rc1. Unfortunately I made a duplicate post of this because I forgot to check first...
I've found out the reason the issue occurs.
Regular taiga biomes generate at [-1.0,-0.450] temperature values with [0.1,1.0] humidity, but frozen rivers, snowy beaches, frozen oceans, and deep frozen oceans also generate in this range, despite being surrounded by non-snowy taigas.
A solution would be to change the frozen rivers to rivers, snowy beaches to beaches, frozen oceans to cold oceans, and deep frozen oceans to deep cold oceans in the [-1.0,-0.450] temperature and [0.1,1.0] humidity range.
I made a datapack using a useful website to test this.

TP: /execute in minecraft:overworld run tp @s 110.99 78.71 1445.22 112.01 16.22
I would attach the datapack, but I don't know if I should or not, so I'm just going to play it safe and not do that. I'm sure Mojang can do it themself if they really want to. If it is requested and allowed though I will attach it to a separate comment.
