From what Murata-san said downthread, it sounds like it is being
changed from _inside_ the style system, by overriding writing-mode in a
user style sheet, or something like that.

Which means that selectors may need to observe computed styles, which
is awkward, but perhaps not out of the question (as long as there is no
circular dependence).
