title: PhpStorm - CSS class name completion
body: <p>I have a HTML file and a bunch of CSS files (bootstrap,.blabla,...)</p>
  
  <p>On html if I call <kbd>Ctrl + Space</kbd> on a "class" attribute the auto-completition work as expected.</p>
  
  <p>But if in this same html file I put some <code>&lt;style&gt;</code> tag with some css definition, the auto-complete just work local and external css files are ignored.</p>
  
  <p>Is this a OK behavior?</p>
