Dialog height bug

When .ui-dialog class has a padding set the dialog is larger that specified by the options

css:

 <div id="thedialog">Dialog Content</div>

 .ui-dialog
 {
   padding: 20px;
 }

 $("#thedialog").dialog({
    height: 200
 });

the dialog should be 200px but it is approx 240px (tested in chrome 12).

All that is needed to fix it is for the line in ui.dialog._size to change:

   nonContentHeight = this.uiDialog.css({
                height: "auto",
                width: options.width
            })
            .outerHeight();
