This fix is not really a fix This will fix the problem...

 // Ensure that missing attributes return undefined
        // Blackberry 4.7 returns "" from getAttribute #6938
        if (elem.attributes == null ||!elem.attributes[ name ] && (elem.hasAttribute && !elem.hasAttribute( name )) ) {
            return undefined;
        }
