Try to support FireGestures (Firefox) and similar gesture extensions in Google Chrome.
These browser extensions/addons maybe(not confirmed) modify
body.scrollTop
orhtml.scrollTop
when scrolling gestures are triggered. Using other element as the scrolling element will fail these gestures.However
document.scrollingElement
is experimental, and not all browsers support it(See MDN). Polyfill (IE 11 tested) was taken from scrollingelement.js.
