allowDefault parameter on Touch.enable() not working?

[danzen]

Hi folks, I am trying to scroll a simple CreateJS stage on iOS and it will not respond to touch to scroll the document page in Safari. Here is a test page: http://zimjs.com/code/iframe/createjs.html

I have createjs.Touch.enable(stage, false, true); and the true is supposed to turn allowDefault to true. But it does not seem to be working. The same test with just a canvas is here: http://zimjs.com/code/iframe/index.html and touch works on the canvas to scroll the document.
