<p><a href="http://bugs.jqueryui.com/ticket/4286">jQuery UI #4286</a> - When the <code>grid</code> dimensions have different values it will break <code>containment</code>.  To recreate simply resize the box to the south; the <code>resizable</code> will leave its <code>containment</code>.</p>

<div id="parent">
    <div id="child"><div>
</div>
