title: Popover does not get anchored to the triggering element
body: <p>So my <code>Twitter Bootstrap</code> <code>popovers</code> seem to be positionally challenged when the triggering element is contained within an element with the style <code>-ms-overflow-y: auto;</code> (a scrollable element within the window).</p>
  <p>When the element is scrolled, the popover does not scroll with it.</p>
  <p>I would really like the popover to move with the content within this scrollable element.  How can I achieve this?</p>
  <p>popover code:</p>
  <pre><code>$(this).popover({
              animation: false,
              html: true,
              placement: popover.placement || 'auto bottom',
              title: popover.title,
              content: popover.validationMessage + popover.content,
              trigger: 'manual',
              container: '.content-panel'
  }).click(function (e) {
                  $('BUTTON[data-toggle=&quot;popover&quot;]').each(function (index, element) { $(this).popover('hide'); });
                  $(this).popover('show');
                  $('#' + $(this).attr('data-for')).focus();
              });
  </code></pre>

  <p><code>.content-panel</code> is the scrollable element.</p>

  <h2>Update</h2>
  <p>I would like the popover to continue floating overtop the other elements.  When using <code>position:relative;</code> on the parent element it contains the popover instead of letting it float over top.</p>
