            Bug ID: 261852
           Summary: [WebGPU]
                    https://webgpu.github.io/webgpu-samples/samples/render
                    Bundles does not load
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mwyrzykowski at apple.com

https://webgpu.github.io/webgpu-samples/samples/renderBundles does not load due to:

MSL compilation error: Error Domain=MTLLibraryErrorDomain Code=3 "program_source:65:48: error: call to 'max' is ambiguous
    vec<float, 3> local8 = saturate((local5 + (max(dot(local3.normal, local6), 0) * local7)));


corresponding MSL:
  vec<float, 3> local8 = saturate((local5 + (max(dot(local3.normal, local6), 0) * local7)));

corresponding WGSL:
  let lightColor = saturate(ambientColor + max(dot(input.normal, lightDir), 0.0) * dirColor);

looks like the ".0" is being dropped, if we kept it, it would compile or at least not fail at this line
