`cosole.error` for passive event listener in Chrome54+

[sculove]

I test iScroll demo file in Chrome55. I'm face a error message.

There is an error in this code.

document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);

cause

If an event listener is added to the document, body, or window and is a scroll blocking (touchstart, touchmove) listener it will be have passive options to be true and we will face a following error

• EventListenerOptions : https://github.com/WICG/EventListenerOptions/blob/gh-pages/explainer.md

As for the warning from Chrome: sorry for the trouble, this is a breaking change in Chrome 56 to improve scroll performance. There's probably a missing touch-action CSS rule, which is necessary to support touch on IE/Edge anyway.
