The same mismatch also prevents Syriac text from actually shaping.
Syriac shaping works in m17n with the required setup in
composition-function-table and using the Meltho fonts. With Harfbuzz it
doesn't work, unless I change "syriac" to "syrc" in charscript.el, just
for testing of course.
As a success story OTOH, Mandaic, using the Noto font, works OOTB ;-)
