title: Should display:none element still have length = 1?
body: <p>I'm just wondering if an element with <code>display: none</code> should have a length of 1 in JavaScript. I though <code>display: none</code> was like removing an element from the document and the known universe.</p>
  
  <p>e.g.</p>
  
  <pre><code>$('.element').hide();  // jQuery sets to display: none;
  console.log($('element').length); // returns 1
  </code></pre>
