title: offsetTop issue in IE with parent elements
body: <p>I have an input field inside a div. When I set the div's style property to display:none, then the input inside the div must return offsetTop == 0. This is the case in FF, Opera, Safari and others, but not IE. </p>
  
  <p>After several hours of research I failed to locate a method to check if a nested element is visible or not in IE.</p>
  
  <p>p.s. Javascript Problem</p>
