Item drop zone when connecting lists through tabs

Item drop zone when connecting lists through tabs


When connecting sortable lists through the tab widget like in this
demo...
http://jqueryui.com/demos/sortable/connect-lists-through-tabs.html
...the interaction is a little strange if the list item is set at 100%
width. The only way to drop it on the tab is to 'grab' the very center
of the list item and move it over the tab. If you drag the list item
from the far left or right side it is very awkward to try to get the
center of the list item to hover over a tab.
Is there a way to have the position of the mouse cursor dictate the
drop event? I think this is a more natural interaction.
thanks for any help,
