Opening up the console, it seems this page depends on the dual-source-blending feature (which we haven't yet implemented, see bug 1924328), but the diagnostic is not what I was expecting:
Uncaught TypeError: GPUDevice.createRenderPipeline: 'src1-alpha' (value of 'dstFactor' member of GPUBlendComponent) is not a valid value for enumeration GPUBlendFactor.
I was expecting a device feature rejection warning here. Maybe the application isn't requesting it, and it should? I see WGPU WASM symbols here, and I suspect that may be out-of-date; WGPU's dual-source blending implementation only recent became spec-compliant, see wgpu#6402.
I'm also getting internal errors for shader compilation on Metal when using macOS:

After some experiments with implementing dual source blending, this app runs into another well-known issue: shadowing in WGSL (viz., bug 1961248):

I'm also getting consistent crashes in surface presentation on macOS unless I set dom.webgpu.allow-present-without-readback to false. 🤔 CC :sotaro, :jimb. I don't have a crash stack yet, but I'm trying to get one.
