Steps to reproduce

Summary:
Edge doesn’t place bopomofo tone marks next to ruby annotations correctly when the tone mark’s position is adjusted using OpenType features ‘vkrn’ or 'vert’.

Steps to Reproduce:
Open the test cases:
‘vkrn’ test case: https://bobbytung.github.io/Bopomofo_on_Web/case05/index.html 

‘vert’ test case: https://bobbytung.github.io/Bopomofo_on_Web/case06/index.html

Expected Results:
Tone marks placed to the right of the ruby annotation, as seen in Firefox 59 or Chrome 65 (screenshots attached).

Actual Results:
Tone marks appear far underneath the ruby annotation in an incorrect orientation. There is also too much spacing to around the ruby annotation’s characters (screenshot attached).
