Re: [fullscreen] Cannot scroll in IE11 while in fullscreen by Fullscreen API (#23)

Actually, one difference I just found. If you have, say, `overflow: scroll;` on `<body>`, and the default `overflow: visible` for `:root`, when you request fullscreen on `document.body`, whether the scrollbars appear depends on the wording.

For `:root:fullscreen-ancestor { overflow: hidden !important; }` approach, the `body` element will have its scrollbar, however, if we "manually" hide the viewport scrollbar instead of using the style, there would not be any scrollbar, becasue in that case, [the `overflow` property of `body` is propagated to the viewport](http://www.w3.org/TR/CSS2/visufx.html#overflow).
