Description Andreu Botella 2022-02-08 13:06:50 PST 
If you submit a form by clicking on an <input type="image"> control, the x and y position of the click will be in the form's entry list, but the submitter field in the submit event will be null.

Per the spec, this is not supposed to happen, since step 6 in the image input activation behavior (https://html.spec.whatwg.org/multipage/input.html#image-button-state-(type=image):input-activation-behavior) runs the form submission algorithm "from the element", i.e. with the <input type="image"> element as the submitter.
