glTF Sample Viewer seems to be an outlier in how it handles lighting for normalTextures being rotated with KHR_texture_transform (bottom row).
Should we be rotating the tangent space for the model? For more context on lighting rotated normal maps, please see the comment here by @emackey https://github.com/KhronosGroup/glTF-Sample-Assets/issues/153#issuecomment-2484079933
