Why can't I programmatically scroll to a given row in a YUI ScrollingDataTable?

Question

It appears the ScrollingDataTable scrollTo method is broken.

As an alternative, I've tried scrollIntoView() and jQuery's scrollTop on the correct dom elements without luck. I've also tried YAHOO.util.Scroll and it doesn't work either.

The datatable is in a div that has a vertical scrollbar.

jQuery version:

var scrollToThisRow = dataTable.getTrEl(recordToScrollTo);
var scrollPos = $(scrollToThisRow).position().top;
$('#tableBodyDiv').scrollTop(scrollPos);

Here's what I tried using YAHOO.util.Scroll:

var scrollToThisRow = dataTable.getTrEl(recordToScrollTo);
var scrollPos = $(scrollToThisRow).position().top;
var attributes = { 
  scroll: { to: [0, scrollPos] } 
};
var anim = new YAHOO.util.Scroll($('#tableBodyDiv'), attributes);
anim.animate();
