The HoverMenu closes when trying to select one of the DropDownList items in the Panel

To reproduce the bug : create a Panel with a DropDownList, add a HoverMenuExtender to your page, set the Panel as its PopupControlID.

Then try to select one of the items in the DropDownList. The HoverMenuExtender disappears.
