Sortable divs contained in hrzAccordion panel fail to disappear when secondary accordion panel is clicked.

Note that this action works correctly in Safari 3 and FFox.

In IE7, the headers for the sortables remain floating over the accordion handles/content. The balance of the sortables disappear as expected. Further attempts at sorting the sortable boxes after clicking an accordion panel that does not contain the boxes fail.

To reproduce, take the demo sortable boxes at:

and place it in an hrzAccordion component panel. Then click on a handle for another panel.
