Created attachment 113664 [details] shows what is now displayed on the panel instead of an icon Prior to the update, the widget displayed as an icon. Clicking on the icon (when panel is at top of screen) showed a dropdown list of the folder's contents. Double-clicking on a file opened the file using the appropriate application. Now the widget is displayed as a link to the folder and functions as such so that when you click on it, the folder opens in Dolphin.
