Anisotropic filtering does not apply to fluid textures

[Alevam-Inc]

The anisotropic filtering setting works with all game surface textures except for fluid surfaces such as water, mud, slime, etc. All I get is standard, blocky mipmapping.

To Reproduce
Enable Anisotropic filtering in the graphics settings menu.

Expected behavior
Anisotropic filtering to be applied on all game surface textures.
