title: CKEditor .focus() in instanceReady event is not working
body: <p>I am having problems in setting the focus in instanceReady event of CKEditor 3.4.1. I have already tried the following two ways but both of them are not always working. </p>
  
  <pre><code>CKEDITOR.on('instanceReady', function(e) { CKEDITOR.instances.editor1.focus(); });
  
  
  CKEDITOR.replace('editor1',
  {
      on :
      {
          instanceReady : function( ev )
          {
              ev.editor.focus();
          }
      }
  } );
  </code></pre>
