The file /touch/src/dom/Element.traversal.js, which is not referenced anywhere in the docs, overwrites the Element.select implementation referenced in the docs with this one:

Code:
    select: function(selector, composite) {
        return Ext.dom.Element.select(selector, this.dom, composite);
    }
...which gets the parameters to Ext.dom.Element.select wrong, causing the select to find elements across the entire document rather than within the scope of the element
