The bug
When going underwater in different biomes, you see a different background color. This color corresponds to the color of the water when seen from above. But when you turn biome blend on (in the example pictures to 15x15), then the color of the water as seen from above changes, but the color seen from underwater does not adjust.

Still not fixed. The fog color still doesn't vary depending on biome blend, as only one biome could affect fog color at a time.
Does this affect 1.13-pre4? If so, update your issue accordingly.
