Terrain generation sometimes generates different land biomes between 1.12.2 and 1.13

When I compared terrain generation between 1.12.2 and 1.13.pre-1, there were some differences in the biomes. This will cause undesirable chunk discontinuities when upgrading old maps. For example, a Forest biome in 1.12.2 becomes an Ocean biome in 1.13.
