Checking toneMapping extended code is wrong?

[greggman]

webgpu-samples/sample/particles/main.ts

Line 351 in 586b141

context.getConfiguration().toneMapping.mode !== 'extended'

The spec says

This spec requires supporting HDR via the toneMapping option. If a user agent only supports toneMapping: "standard", then the toneMapping member should not exist in GPUCanvasConfiguration, so it will not exist on the object returned by getConfiguration() and will not be accessed by configure()). This allows websites to detect feature support.

This means the code above will get

Cannot read properties of undefined (reading 'mode')

on browsers that don't support this.

I can reproduce in Firefox Nightly indeed. Thanks for catching this!

This was discussed on #455, we just never fixed it.
