Hi Richard!
This section has been rewritten to fix various errors and improve
white space handling. I'll answer based on the new text.

http://dev.w3.org/csswg/css-ruby/#anon-gen-bare-inlines
“Wrap misparented inline-level content: Any consecutive sequence of
text and inline-level boxes directly parented by a ruby container
or ruby base container is wrapped in an anonymous ruby base.”

No, because an <rb> is a ruby base box: it shouldn't be wrapped
in an additional ruby base box.

No, because the <rb> element is a ruby base box: we don't generate
any anonymous wrappers within a ruby base box.
