Sortable: 'update' doesn't fire when first item in one list is moved to the first position in connected list

Discussion: http://groups.google.com/group/jquery-ui/browse_thread/thread/4ba439aef4805e70/dc3314492a6db8fb

(I thought it might be helpful to have a log of the bug here in Trac. Sorry if you've already fixed it!)

Example: http://www.justinstayton.com/sortablesTest.html

Move 'Latest Sermons' or 'Latest Articles' to the beginning of the other list, and you'll see that 'update' only gets fired on the receiving list.
