unable to postMessage with webassembly module

[treethought]

related to #9140, which was closed as structured cloning had not yet been implemented.

Now that #3557 has been implemented, I would expect the following to work given the following documentation:

• A WebAssembly.Module object representing the compiled WebAssembly module.
  * This Module can be instantiated again, or shared via postMessage().

deno versions: 1.12.2 and 1.13.1

main.ts

const worker = new Worker(
  new URL("./worker.ts", import.meta.url).href,
  {
    name: "wasmWorker",
    type: "module",
  },
);

const wasmBuf = Deno.readFileSync("./test.wasm",);

const valid = WebAssembly.validate(wasmBuf);
console.log("valid", valid); // => true

WebAssembly.compile(wasmBuf).then((mod) => {
  console.log("sending module to worker");
  worker.postMessage({ "module": mod });
}).catch((err) => {
  console.log(err);
});

worker.ts

onmessage = function (e) {
  console.log("module received from main thread");
  console.log(e.data);
};

Result

➜ deno run -A test.ts
valid true
sending module to worker
DOMException: Failed to serialize response

Note that in the context this minimal example is based on, the message is DataCloneError: Failed to serialize response
