title: Find Codeception elements with more than one CSS class
body: <p>i have something like the following markup:</p>
  
  <pre><code>&lt;body&gt;
    &lt;div class="navigation"&gt;...&lt;/div&gt;
    &lt;div class="messages error"&gt;...&lt;/div&gt;
    &lt;div class="content"&gt;...&lt;/div&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>Now I have some codeception tests (with PHPBrowser Module), to check, if the "div" with messages is not existing. This doesn't work for container with more than one class. They don't seem to be match with this:</p>
  
  <pre><code>$I-&gt;dontSeeElement('.messages');
  $I-&gt;dontSeeElement('.error');
  $I-&gt;dontSeeElement('.messages .error');
  $I-&gt;dontSeeElement('div.messages.error');
  </code></pre>
  
  <p>How can I match this container?</p>
  
  <p>Regards
  Sebastian</p>
