    selections: Remove the "inconsistent" state when not needed
    
    Remove the "inconsistent" state when the user toggles a collection.
    
    According to the docs for GtkToggleButton:
    
    "Normally you would turn off the inconsistent state again if the
    user toggles the toggle button. This has to be done manually,
    gtk_toggle_button_set_inconsistent() only affects visual appearance,
    it doesn’t affect the semantics of the button."
    
    Closes: #3
