Ext.Function.createBuffered ignoring arguments

[pleszczynski]

ExtJS 4.0.7, Firefox 7.0.1.

Ext.Function.createBuffered function ignores arguments passed to buffered function.
Example:

fun = function() {
  console.log(arguments);
}
fun2 = Ext.Function.createBuffered(fun, 100);
fun2(1, 2, 3);

Expected:

[1, 2, 3]

Got:

[ -12 ]

    createBuffered: function(fn, buffer, scope, args) {
        return function(){
            var timerId;
            return function() {
                var me = this;
                if (timerId) {
                    clearTimeout(timerId);
                    timerId = null;
                }
                var args2 = arguments;
                timerId = setTimeout(function(){
                    //fn.apply(scope || me, args || arguments); //WRONG
                    fn.apply(scope || me, args || args2); //CORRECT
                }, buffer);
            };
        }();
    },
