GLTF model with WebP texture and Mipmapping renders incorrectly on Android

I've encountered a rendering issue with a GLTF model that appears to be specific to Android devices when using a WebP texture with mipmapping.

A GLTF model's texture fails to render correctly on Android. The issue only occurs when the material's texture sampler uses a mipmap-based minification filter (e.g., LINEAR_MIPMAP_LINEAR). The same model renders perfectly on macOS, Windows, and iPadOS. Disabling mipmapping resolves the issue on Android.

When viewed from a distance, the model appears completely black. As the camera approaches the model, the texture gradually becomes blurry and bright, centered around the camera.

This issue was also observed in the PlayCanvas Editor.

Platforms Tested

• Android (Google Pixel 7, Chrome): Bug occurs.
• macOS (Macbook Air, Chrome): Renders correctly.
• Windows (Chrome): Renders correctly.
• iPadOS (iPad Air 4, Chrome): Renders correctly.

I was able to resolve the issue on Android by modifying the failing model's GLTF file. By changing the sampler's minFilter from 9987 (LINEAR_MIPMAP_LINEAR) to 9729 (LINEAR), the texture now renders correctly on Android.

Start by reproducing the reported GLTF case on Android with the WebP texture and minFilter 9987 (LINEAR_MIPMAP_LINEAR), then compare it with 9729 (LINEAR). Trace the texture and mipmapping path used by the engine; done means the mipmapped model renders correctly on Android without disabling mipmapping.
