Version:

deno 1.42.0 (release, x86_64-pc-windows-msvc)
v8 12.3.219.9
typescript 5.4.3

Problem

I tried to run the webgpu demo program (https://github.com/denoland/webgpu-examples/blob/main/hello-compute/mod.ts) using command deno run --unstable-webgpu --allow-read --allow-write mod.ts. The original code works well, but when I try to use float16 in computer shader, I get no output [ "0", "0", "0", "0" ] with no warning or error messages.
The only modification I did was:

const device = await adapter?.requestDevice({
  "requiredFeatures": ['shader-f16'],
});
...
const shaderCode =  `
  enable f16;
  @group(0)
...

I get no output no matter using data type Uint32Array, Float32Array or Float16Array(from https://deno.land/x/[email protected]/src/index.mjs). But in chrome canary, the same code works.

Could anyone please tell me if deno doesn't support f16 in WebGPU currently, or something else goes wrong? Thanks a lot.
