HTMLFormElement.elements should not return images

• Component: Forms
• Status: RESOLVED DUPLICATE

[Marvin Scholz]

According to https://html.spec.whatwg.org/multipage/forms.html#category-listed the HTMLFormElement elements
property should not list img elements in forms, this does seem to work fine, except when explicitly accessing by ID.

For example given the following HTML:

    <form id="test_form">
        <input type="text" name="example_text_input">
        <img alt="example" id="test_img" width="10" height="10" src="…">
    </form>

Querying the elements with the img id like this:

    document.forms['test_form'].elements['test_img']

should return undefined, like it happens in other browsers (tested with Firefox and Chrome), but it actually returns the img element.
