    status: Use fixed sorting of input sources on empty MRU
    
    When updating the MRU sources if there was no prior MRU, we want
    to go with the unmodified list of sources in visibility order.
    
    However iterating over object properties happens in an undetermined
    order, so the initial MRU list ends up picking a value at random.
    
    In order to prefer the sources list in the same order than they
    appear in the menu if there was no prior MRU, order the keys
    when accessing it and building the initial list of sources.
    
    Closes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5873
