Xenova/whisper-webgpu · unresolved call target 'unpack4xU8' on Chrome 120

The demo is not working for me on MacOS with Chrome (120.0.6099.234 (Official Build) (arm64)).

According to chrome://gpu/ I have "WebGPU: Hardware accelerated"
I also checked Chrome WebGPU troubleshooting tips.

I also checked out the transformers.js code (v3 branch with commit id c3909366c789c15a01d3b42e639ee567809f00c2) and got the same errors.

Tint WGSL reader failure: :62:44 error: unresolved call target 'unpack4xU8'
            let b_value_lower: vec4<u32> = unpack4xU8(b_value & b_mask);
                                           ^^^^^^^^^^
