Button plugin doesn't apply "checked"-attribute to checkbox/radio button

[Studio384]

The button example as described in the documentation (http://v4-alpha.getbootstrap.com/components/buttons/#checkbox-and-radio-buttons) doesn't apply the checked-attribute to the actual checkbox and only applies active to the button.

Same problem also for the radio buttons that follow.

Actually, on further analysis no browser ever changes the checked attribute in the DOM (even on vanillla checkboxes/radio buttons), so just doing something like "inspect element" and looking at the DOM, or querying with document.getElementById('option1').getAttribute('checked') or similar, will not show any change. It's the checked property that changes, however ... (e.g. document.getElementById('option1').checked), and this works properly with the button plugin.
