Description
WGSL specification:

User-defined vertex outputs and fragment inputs of scalar or vector integer type must always be specified with interpolation type flat.

Chrome WebGPU enforces this, but wgpu/naga does not, resulting in an application that fails under the WebGPU backend only.

Platform
wgpu 24.0.0, but also trunk
