title: Embedded font in Alert font-family property doesn't working in Flex 4
body: <p>I'm using Flex 4. I'm trying to apply a embedded font in all Alert components of the application, to get the same style that all the app, of course.</p>
  
  <p>I code in my CSS file:</p>
  
  <pre><code>@font-face
  { 
  fontFamily: "Trebuchet MS";
  src: url("resources/Trebuchet MS.ttf");
  embedAsCFF: true;
  }
  mx|Alert{   
  font-family: "Trebuchet MS";
  } 
  s|ButtonBase, s|TextBase, s|TextInput, mx|Label{
  font-family: "Trebuchet MS";
  color:"#000000";
  }
  </code></pre>
  
  <p>The font-family worked to all componentes, but not to the Alert component. In alert the text message and title got unvisible. If I change to other font-family it works correctly, just the embedded font doesn't work on Alert component. Anyone got this problem?</p>
  
  <p>Obs: The embedded font worked in all the app, just the Alert no.</p>
