Input "selectionStart" is not used in `userEvent.type(input, "abc")`

As mentioned in title changing selectionStart has no effect when using userEvent.type(input, "foobar"), eg:

test("selectionStart is not used when updating input", async () => {
  const { getByTestId } = render(<App />);
  await waitForElement(() => getByTestId("testinput"));

  const input = getByTestId("testinput");
  expect(input).not.toBeNull();
  expect(input.value).toBe("xyz");

  // move cursor to the beginning of input
  input.focus();
  input.setSelectionRange(0, 0);
  expect(input.selectionStart).toBe(0);
  expect(input.selectionEnd).toBe(0);

  // start typing
  await userEvent.type(input, "abc");

  expect(input.value).toBe("abcxyz"); // <-- FAILS
  expect(input.selectionStart).toBe(3);
});

Important: in the test case I use react-scripts test --env=jsdom-sixteen as jsdom had fixed selectionStart only recently https://github.com/jsdom/jsdom/issues/2787

Test case on codesandbox:

This is now supported 😃

Hmm, I just wished you could just sent the letter to jsdom and let it append it to the value but that doesn’t seem possible. I am wondering how an actual browser deals with this though. How regarding the event flows? Does it call setRangeText somehow? Anyways I have been lately working on a new version of type() but would be great to have this sorted before this new version.
