md-menu scrolls to top when an item is selected

[Magador]

Demo: http://codepen.io/Magador/pen/ZbmeRo

When selecting an item or dismissing the opened menu, the page scroll to its top.
The bug happens on Chrome 48, IE 11, but not on Firefox 42.

It seems that body.scrollTop = scrollOffset in src/core/util/utils.js#L254 cannot be changed

Edit: I overcame the bug by setting

body  {
    height: auto;
}

because it's set at 100% in src/core/style/structure.scss#L2
