Custom biomes are broken on android devices (since new Caves&Cliffs world gen - on all devices). Climate, water surface color, water fog color, biome fog color are not working correctly (and you no longer can get access to it with the experimental features).

Steps to Reproduce:
1. Create an addon with your custom biomes (biomes must contain different values of climate, fog and water colors);
2. Add add-on to your world;
3. Look for custom biomes.

Observed Results:
Biome colors (grass, foliage, water, fog) mixes between different custom biomes.

Expected Results:
Biome colors (climate etc.) must math the code.

Broken components:

1. "minecraft:climate" ([behavior_pack_name]/biomes/[biome_name].json)
Description: the color of grass or leaves applies the wrong value in the biome or “mixes” with other custom biomes and applies to them. When specifying a value

"downfall": 0.4, "snow_accumulation": [ 0.0, 0.125 ], "temperature": 1.6

snow instead of rain; grass and foliage will be blue or gray.

Ash particles.
Ash particles are identified in the biome with their parent climate value.

2. "water_surface_color" ([resource_pack_name]/biomes_client.json)
Description of the problem: often the value of the custom biome takes the default biome value. For example:

 "custom": {
    "water_surface_color": "#ffffff"
 },

 "default": {
    "water_surface_color": "#aaaaaa"
 },

The value of "custom" biome in the world:

"#aaaaaa"

Rarely does the value of a custom biome apply to another custom biome. For example:

"custom": {
    "water_surface_color": "#ffffff"
 },

 "custom2": {
     "water_surface_color": "#aaaaaa"
 },

The value of "custom2" biome in the world:

"#ffffff"

3. "water_fog_color" ([resource_pack_name]/biomes_client.json)
Description of the problem: has the same problem as the component "water_surface_color".

4. "fog_color" ([resource_pack_name]/biomes_client.json)
Description of the problem: has the same problem as the component "water_surface_color".
