Do not prevent default move and touch event to scroll HTML page within Cocos Canvas

Cocos Creator

hi, i embed Cocos Canvas to my HTML page.
when the page goes overflow then the scroll will appear.

problem is that while mouse position is inside Cocos Canvas it can’t be scrolled and on mobile phone it can’t be scrolled by touching inside the Canvas.

is it possible to allow default event from mouse and touch to scroll the page as normal within Cocos Canvas?
if so how to implement that?

Thanks,

solve that by break the library
remove i.preventDefault() from cocos2d-js-min.js
