Embedded problem with g2_highlightId

If my URL to the embedded page http://www.tatankanation.org/tiki-g2.php?g2_itemId=2446&g2_highlightId=7708 includes the g2_highlightid then I get a blank page. If I call the same thing in the non-embedded http://www.tatankanation.org/gallery225/main.php?g2_itemId=2446&g2_highlightId=7708 it works fine.

This is using 2.3RC1.

For now I added code to remove the g2_highlightId, and the page displays fine.

//
// remove the request for g2_highlightId
//
if (isset($_REQUEST['g2_highlightId']))
{
   unset($_REQUEST['g2_highlightId']);
}
if (isset($_GET['g2_highlightId']))
{
   unset($_GET['g2_highlightId']);
}
