    <table style="width:100px;height:100px;border:inset">
        <tr>
            <td onclick="displayAlert(this)">Content.</td>
        </tr>
    </table>
    <p>Click anywhere inside the table element and you should get an alert telling you so.</p>
    <p>Bugzilla 3662 was that clicking in non-content did not fire onclick handler.</p>
