Shader on water prevents color change

Release_516590

Summary:
When trying to change the texture of water it remains blue. The texture of the water changes but is overlaid with a blue tint. It is caused by the shader used on water which gives the texture colour based on biome, brown in swamps etc. This differs from Java as no shader existed and thus the color of the texture was seen in-game.

Impact:
This prevents the use of custom colored water in texturepacks and maps. For one of our maps in development this is a vital feature and thus blocks it from being released.

Repro Steps:
1. Load a world with the mcpack attached to this report equipped
2. Change gamemode to be in creative
3. Fly around until you find water,
3b. or Place a water bucket from your creative inventory

Observed Results:
The difference in the color of the water is vastly different using the same texture in Java and bedrock. Bedrock has the blue tint nearby which goes closer to the actual color further away, whereas Java just takes the texture directly.

Expected Results:
Bedrock to not apply a blue tint on the texture.
