    app: make sure the GimpContainerPopup shows the right item as selected…
    
    … for the case of data managed by the GimpContext.
    
    Checking stable and dev builds, it looks this just never worked and used
    to just show no selection. Now it is more annoying as it shows a
    selected item, but not the right one. Just make sure it shows whatever
    is currently selected.
