Late answer:

A simple solution is to add an event handler for the TargetUpdated event, and set NotifyOnTargetUpdated=True on the ItemsSource binding:

and in the event handler, scroll to the top item:

private void ListBox_TargetUpdated(object sender, DataTransferEventArgs e)
{
    if (listBox.Items.Count > 0)
    {
        listBox.ScrollIntoView(listBox.Items[0]);
    }
}
