    workspace-indicator: Exclude DESKTOP windows from window previews
    
    While nautilus removed its desktop support a while ago in favor of an
    extension, it's still possible that some external X11 desktop icon app
    is used. As DESKTOP windows cannot be moved between workspaces or stacked,
    and aren't perceived as regular windows, it doesn't make sense to show
    them as previews in the workspace switcher.
