title: dojo.byId() works but dijit.byId() doesn't
body: <p>I have a select field with id <code>appointment_stylist_id</code>. For some reason, the first one of these returns my element but the second one returns <code>undefined</code>:</p>
  
  <pre><code>  console.log(dojo.byId('appointment_stylist_id'));
    console.log(dijit.byId('appointment_stylist_id'));
  </code></pre>
  
  <p>Any idea why?</p>
