fireEvent for PointerEvent only receives Event minus my set options

Question

I'm trying to send a PointerEvent to my code for testing. This is a pointerDown but I've seen the same problem with pointerMove as well as pointerUp

// Fake primary mouse down input
    fireEvent.pointerDown(domElement, {
      button: MouseButton.Primary,
      clientX: 5,
      clientY: 5,
    });

When I receive the event to my handler event.button, event.clientX and event.clientY are all undefined.

I confirmed that using this the same way for a WheelEvent works as expected.

Am I doing something wrong in this instance specifically?

On the assumption that you are testing in a JSDOM environment, the problem here is that JSDOM does not, at time of writing, support setting the event properties when creating pointer events. See this testing library issue and this JSDOM PR which should resolve the issue but can't yet be merged. A workaround is suggested in the testing library issue.
