I don't think that old bug is related to what you see, for two
reasons:

  . the bug was in libm17n-flt, and you are using HarfBuzz
  . the basic rule that Emacs only composes characters supported by
    the same font doesn't depend on the text-shaping engine, so it
    cannot be fixed in one particular engine

You need to find a better font.
