Description

d.sizeOf(d.size(32, d.u32))

returns 32.
But in generated WGSL, it is no-op so size is 4.

Research direction

Start by reproducing the d.sizeOf(d.size(32, d.u32)) example and inspect how d.sizeOf and d.size are handled when generating WGSL. Compare the reported size with the emitted WGSL behavior; done means sizeOf reports the actual generated size of 4 for this non-field case.
