The ruby-position inherits, but display doesn't. If we make the
computed value of 'writing-mode' of the ruby annotation container to
be 'vertical-rl', that should inherit to its descendants. Does this

I chose 'vertical-rl', since it's the natural vertical flow in Taiwan,
where the inter-character is used. It could also reduce the
interoperability risks if 'sideways' is ever used.

Fix is here:
