馃崚 Folder View: fix label rendering for popup and widget views
The shadow only needs to be displayed on the desktop, in containment mode. Previously we were checking only for whhether or not the widget was in list mode, which missed the case of grid mode for standalone widgets and folder popups on the desktop.
