That's probably the problem.  I have Version 1.171 of the font, and the
closest is comes to layout support for Myanmar is empty lists of
lookups for undefined script "myan".  The script tag should be "mymr",
so HarfBuzz applies no script-specific shaping.  There may be other
issues, as changing "myan" to "mymr" doesn't fix the problem.
