body: <p>How do I set the font size of text in a title bar in ST2?</p>
  
  <p>I've tried the 'style' attribute but that affects the text of buttons in the toolbar too and they are then rendered smaller if the font-size is smaller.  I only want to set the text of the caption within the toolbar not everything including the buttons.</p>
  
  <p>Does anyone know how this can be accomplished?</p>
