I updated harfbuzz to 4.2.1 (and upgraded freetype after that) and the
output is byte-identical to the earlier version 3.0.0.  I'm not sure
what I'm missing.

a few more notes to self: The Khaiti number signs also compose only
linearly in emacs and only when I use the same font for numerals, say:

(set-fontset-font "fontset-default" '(#x966 . #x96f)  "NotoSans Kaithi"

Otherwise I can't see glyph for #x110bd whic precedes a number, I only
see a thin vertical empty box rendered.

Likewise for the newly installed composition rules, I can only see
them with the Siddhanta font. All the other fonts that display
devanagari seem to show the thin empty vertical box to render the
stress accents.
