title: Class in select_tag not loading on page load
body: <p>I've got the following select tag:</p>
  
  <pre><code>= select_tag 'rights', options_for_select([["User", "user"], ["Editor", "editor"], ["Admin", "admin"],], current_rights), {class: 'selectpicker'}
  </code></pre>
  
  <p>The select tag works, but for some reason the class isn't loading when I load the page for the first time.</p>
  
  <p>However when I refresh the page, the class does load.</p>
  
  <p>Any ideas?</p>
