title: Display Iframe with colorbox, url with parameters does not work
body: <p>I'm new to the site so please forgive me if I make some mistakes. And I'm also sorry about my bad English.</p>
  
  <p>I'm trying to display an Iframe Colorbox from a dropdown list, it works well like this:</p>
  
  <pre><code>&lt;?php 
  foreach($entities as $entity =&gt; $value) 
   {
     echo '&lt;option value="'. $value .'" class="iframe" href="http://mysite/index.php"&gt;'. $entity .'&lt;/option&gt;';
   }
   ?&gt;
  </code></pre>
  
  <p>However, if I try to use some URL with parameters like:</p>
  
  <p><code>mysite/index.php?title=Special:UserLogin&amp;returntoquery=mobileaction%3Dtoggle_view_mobile</code></p>
  
  <p>The Iframe will not show anymore. Can anyone please tell me how to solve this problem? </p>
