title: Ace editor: everything works except being able to type text into the editor
body: <p>For the life of me I can't figure what the problem is. Using the latest Ace editor and it shows up just fine, I can even place the cursor where I want, but I just can't type anything into the editor. Configuration is quite vanilla:</p>
  
  <pre><code>var html_editor = ace.edit('html_editor');
  
  html_editor.$blockScrolling = Infinity;
  html_editor.getSession().setTabSize(2);
  html_editor.getSession().setUseSoftTabs(false);
  </code></pre>
  
  <p>As for background; I use it within a WordPress plugin that disables all of the other scripts that WordPress loads by default so the only script running is the Ace editor. Console is empty and there are no warnings. I've tested with the latest Safari for Mac, Chrome for Mac and Firefox for Mac.</p>
  
  <p>All help is appreciated.</p>
