title: dojo tabs show up as regular divs first then suddenly change to the tab format
body: <p>I'm using dojo tabs in a php file. When the php file is first written to the browser the tabs show up as regular divs in a big mess. Then a second later they are fixed nicely into tab form. It's been a while since I looked into dojo and at the time it was written it was using 1.6 using links to online versions of dojo.</p>
  
  <p>Is there some reason that this would happen. Something not ready or something not loaded first?</p>
  
  <p>the php code echos this html:  </p>
  
  <pre><code>&lt;div dojoType='dijit.layout.TabContainer'&gt;&lt;div dojoType='dijit.layout.ContentPane' title='Words' selected='true'&gt;some html&lt;/div&gt;&lt;/div&gt;...etc
  </code></pre>
  
  <p>I have this javascript in the header of the php file to echo this html first.</p>
  
  <pre><code>&lt;script src='http://ajax.googleapis.com/ajax/libs/dojo/1.6/dojo/dojo.xd.js' djConfig='parseOnLoad: true'&gt;&lt;/script&gt;&lt;script&gt;dojo.require('dijit.Tooltip');dojo.require('dijit.layout.TabContainer');dojo.require('dijit.layout.ContentPane');&lt;/script&gt;&lt;link rel='stylesheet' type='text/css' href='http://ajax.googleapis.com/ajax/libs/dojo/1.6/dijit/themes/claro/claro.css'/&gt;;
  </code></pre>
