    I agree that this implies that the system is not conformant with the
    standard. But that could be because the standard is broken. So perhaps
    it is the standard that should be fixed, by specifiying a new preferred
    sequence for isolated combining marks.

    I realise that for backward compatibility reasons the old encoding
    cannot be made illegal. But it can be deprecated, and a note can be
    added that this sequence may not always be displayed as preferred.
