title: How to reset scroll position of modal in bootstrap3?
body: <p>I have a <a href="http://getbootstrap.com/javascript/#modals" rel="nofollow">bootstrap v3 modal</a>, like in the documentation.</p>
  
  <p>When I open the modal for a first time ('Launch demo model' button) a vertical scroll bar is in a top position. If I scroll down and click 'Cancel' in modal it will close. It is ok. But if I open modal again it will be already scrolled down. And this is case which I would like to avoid. What should I do to open modal in a top position?</p>
