title: Ng-submitted not being applied to form
body: <p>According to the docs, forms in angular should apply a "ng-submitted" class when submitted, but I'm not seeing that. In the linked jsfiddle below you can see that even after the submitted button is clicked, the class is not applied.</p>

  <p>edit: I included some code here even though it is pointless, check out the jsfiddle above.</p>
  
  <pre><code>//this is the code i have in the jsfiddle, check it out there.
  &lt;form&gt;
      &lt;button type="submit"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>What am I misunderstanding?</p>
