title: How to set blankText width?
body: <p>i have form with textfield allowBlank=false, and blankText='Inserire il motivo della richiesta'</p>
  
  <p>In Firefox no problem, I read my text correctly:

  <p>In Chrome I get blankText unreadeable because text is shown with small width :

  <p>Anyone can tell me how to set blankText width, so I can read in all browsers?</p>
