Maximum / Restore dosn't work for containment

[fglueck]

If I bind the dialog to a div and maximize it, it will grow up the hole window (this is OK) but if I restore it, it will lost the containment.

.dialog("widget").draggable("option","containment","#frameContent")

I try to fix it with the restore event, but the dlg parameter is an empty Object.
"restore" : function(evt, dlg){ console.log(evt,dlg);

A workaround is:
"restore" : function(evt, dlg){ $(evt.target).dialog("widget").draggable("option","containment","#frameContent") };
