title: KnockoutJS css and class in the same binding
body: <p>Despite the section in <a href="https://knockoutjs.com/documentation/css-binding.html" rel="nofollow noreferrer">https://knockoutjs.com/documentation/css-binding.html</a> i wasnt able to use css and class together, instead I could use two different css bindings: <a href="http://jsfiddle.net/g9sot5qb/" rel="nofollow noreferrer">http://jsfiddle.net/g9sot5qb/</a></p>
  
  <p>Am I doing something wrong or is the documentation inaccurate?</p>
  
  <pre><code>&lt;span class="cls1 cls2" data-bind="text: title,css: {active: active}, class: myClass" &gt;&lt;/span&gt;
  &lt;span class="cls1 cls2" data-bind="text: title,css: {active: active}, css: myClass" &gt;&lt;/span&gt;
  </code></pre>
