title: Why is z-index ignored with position:static?
body: <p>See this comment <a href="http://www.google.com/codesearch#NjeLL32WYDs/trunk/ui/jquery.ui.core.js&amp;q=zindex%20package%3ahttp://jquery-ui%5C.googlecode%5C.com&amp;l=154">from jquery-ui</a></p>
  
  <pre><code>// Ignore z-index if position is set to a value where z-index is ignored by the browser
  // This makes behavior of this function consistent across browsers
  // WebKit always returns auto if the element is positioned
  </code></pre>
  
  <p>I see that jquery's <code>zIndex()</code> returns 0 if the element is <code>position: static</code>.</p>
  
  <p>Isn't z-index supported on position:static? (It works for me in Chrome, haven't tested cross-browser)</p>
