title: CMFCRibbonEdit does not get focus
body: <p>I just added a CMFCRibbonEdit to my ribbon but it seems it does not get the focus.</p>
  
  <p>It appears disabled.</p>
  
  <p>I even copy/pasted an implementation of the creation of this control from a Microsoft sample but I get the same behaviour.</p>
  
  <p>Any idea on what I may be doing wrong or forgetting to do ?</p>
