    No, it's a logical consequence of the fact that CGJ has ccc=0.

    If you check, that's the same ccc as for enclosing marks, so the CGJ
    acts like them to turn the
    preceding sequence into some kind of "unit" to which the following marks

    In essence, the CGJ acts like an invisible enclosing mark when you
    consider its actions relative
    to combining sequences.

    The tricky part is the second base character, but that's been tricky
    since forever.
