New element creation in IE8 with class attribute

[[email protected]…]

If a new element is created and the map of attributes contains the class attribute, an error "Expected identifier, string or number" is logged, and the element isn't created. See ​http://jsfiddle.net/TNfcX/5/ for a working example.

It only doesn't work in IE8 and below.

• class is a reserved word in JavaScript.
• Avoid $(html, props) and use .attr("class", "btn") instead.
