Resizable Containment documentation sample not working

Resizable Containment documentation sample not working


When I test the resizable containment example at
http://jqueryui.com/demos/resizable/constrain-area.html I can resize
outside the containment area when resizing downwards. This happens in
FF & Chrome. I didn't test others. Is this a known bug and if so is
there a workaround? I am having all sorts of trouble getting the
resize containment working on my site and was wondering if others are
experiencing problems also.
Thanks.
