relative pathname in Request not working on POST request

Using the pathname in a GET request everything works fine. Code: 
test("GET: all car brands", async () => {
  const res = await app.request("/api/brand");
  const body = await res.json();
  // [{ id: 0, name: "BMW" }, { id: 1, name: "Audi" }]
});
test("GET: all car brands", async () => {
  const res = await app.request("/api/brand");
  const body = await res.json();
  // [{ id: 0, name: "BMW" }, { id: 1, name: "Audi" }]
});
But using a POST request I get the error: TypeError: Failed to construct 'Request': Invalid URL "/api/brand". 
test("POST: create new car brand", async () => {
  ...
  ...
  const req = new Request("/api/brand", {
    method: "POST",
    body: formData,
  });
  
  await app.request(req);
  ...
  ...

  /*
    41 |     const req = new Request("/api/brand", {
                       ^
    TypeError: Failed to construct 'Request': Invalid URL "/api/brand"
     code: "ERR_INVALID_URL"
  */
});
test("POST: create new car brand", async () => {
  ...
  ...
  const req = new Request("/api/brand", {
    method: "POST",
    body: formData,
  });
  
  await app.request(req);
  ...
  ...

  /*
    41 |     const req = new Request("/api/brand", {
                       ^
    TypeError: Failed to construct 'Request': Invalid URL "/api/brand"
     code: "ERR_INVALID_URL"
  */
});
If I use the absolute server url (like http://localhost:3000/api/brand) it just works fine.

using the test client might be easier than constructing the reqs yourself: https://hono.dev/docs/helpers/testing but my best guess would be that app.request is doing some relative path resolution under the hood that Request doesn't https://developer.mozilla.org/en-US/docs/Web/API/URL
