upsuper has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-ruby] text-orientation of bopomofo annotation ==
Copy from [my email to www-style](https://lists.w3.org/Archives/Public/www-style/2015Aug/0265.html):
> I propose that we should add "text-orientation: upright" to the "rt:lang(zh-TW)" rule.
>
> The reason is that, all the tone marks in bopomofo (U+02CA, U+02C7, U+02CB, U+02D9) have Vertical_Orientation property "R" while the bopomofo characters are all "U". It means, without explicitly setting text-orientation to upright, the text run would break between them, which makes it impossible to use font feature to place the tone mark properly.
