In response to Richard Wordingham,
Sorry I can't answer many of your questions. Hoping someone who can
does. Note that although the proposal gave canonical combining class
zero to both the tone marks and the vowel signs, the on-line Unicode
data gives canonical combining class 230 to the tone marks.

FWIW, neither is dropped in the display here, although they don't
display identically. The first string shows TONE-1 positioned to the
right of MAI KANG, the second string superimposes them. (Windows 7
running LibreOffice in order to enable the USE from HarfBuzz.)

Substituting U+1A36 TAI THAM LETTER NA for BA in the above strings,
ᨶᩴ᩠᩵ᩅᩣ ᨶᩴ᩠ᩅ᩵ᩣ, and trying to get the ligature are in the attached
*.PNG file. Here's the four strings for the PNG:
