Description

I know that blending in WebGPURenderer is now happening in Linear sRGB space but even so the result when rendering to a transparent background looks very wrong, though it's not exactly clear what's going wrong. It looks like a premultiplied alpha issue if I were to guess?

Reproduction steps

1. Set the clear color to a completely transparent value
2. Render a partially transparent object
3. Notice a different blending profile than if a solid background color were used
