Re: [csswg-drafts] [css-writing-modes] Support vertical CJK + ttb Arabic (rtl scripts generally) (#3608)

> As for Sogdian and Old Uyghur, aren't they already supported, as Mongolian and Manchu are, using `writing-mode: vertical-lr`? (and if not, why not?).

@frivoal, it’s because Sogdian and Old Uyghur are RTL in horizontal text and TTB in vertical text, whereas Mongolian is LTR/TTB.

Hieroglyphic Meroitic is another RTL/TTB script, though it’s different in that the glyphs are not rotated in vertical text.
