LibWeb: Do not assume grouped radio buttons have the same parent

Browse Source 
For example:

    <div>
        <input type=radio name=group value=item1 />
    </div>
    <div>
        <input type=radio name=group value=item2 />
    </div>

Is a valid DOM and clicking on of these radio buttons should uncheck
the other.
