title: jquery mobile page transition is not working
body: <p>I have this</p>
  
  <pre><code>            $.mobile.changePage( "mainmenu.php", { 
                  transition: "slide",
                  reverse: true
              });
  </code></pre>
  
  <p>to change pages using a slide, but when I test on my desktop or my phone, it just changes pages instantly without a slide...</p>
