[bug] invoke does not handle Headers correctly

[WSH032]

Describe the bug

tauri/crates/tauri/scripts/ipc-protocol.js

Line 38 in 8a1d490

...((options && options.headers) || {})

...options.headers works for { foo: "bar" } but does not work for a Headers object.

Reproduction

import { invoke } from "@tauri-apps/api/core";

// work ⭐
await invoke("foo", undefined, {
  headers: {
    foo: "bar"
  }
});

// not work ❌
const headers = new Headers({ foo: "bar" });
await invoke("foo", undefined, {
  headers
});

Can't receive foo: "bar" header in backend.

Expected behavior

No response

Stack trace

Additional context

I have not checked the case for isolation mode because I don't quite understand how to use this mode (its documentation is not very clear 😵).

Hey, do you mind give #13227 a try and see if it indeed fixes the problem?
