Myanmar ု U+102F Myanmar Vowel Sign U incorrectly positioned

Font

phaseIII_only/hinted/ttf/NotoSansMyanmar/NotoSansMyanmar-Regular.ttf

Font Version

Version: Version 2.001; ttfautohint (v1.8.2)

Issue

This character is not being correctly positioned when combined with other characters. This issue seemed to be partially reported back in #44

Example: နှု

When tested with the Padauk font on Google Fonts it is rendered as expected

Character data from example

	Unicode character	Oct	Dec	Hex	HTML
န	myanmar letter na	010024	4116	0x1014	န
ှ	myanmar u+0103e	010076	4158	0x103E	ှ
ု	myanmar vowel sign u	010057	4143	0x102F	ု

Here a good example how "နှု" should be rendered https://asiafoundation.org/wp-content/uploads/2020/06/Myanmar-Business-Environment-Index-Covid-19-Impact-on-Businesses-Summary_MM.pdf.
Looks good in Serif.

Just wanted to add to the above post that there are two more combinations that have the same problem. All of the version 2.001 fonts, both Noto Sans and Noto Serif have this problem.

1. နှူ
2. နှို

This is the character data from these two combinations.
Combination 1:
န MYANMAR LETTER NA U+1014
ှ MYANMAR CONSONANT SIGN MEDIAL HA
ူ MYANMAR VOWEL SIGN UU

Combination 2:
န MYANMAR LETTER NA U+1014
ှ MYANMAR CONSONANT SIGN MEDIAL HA
ိ MYANMAR VOWEL SIGN I
ု MYANMAR VOWEL SIGN U

Serif is fixed, sans is not.
