Yeah this case fails "on purpose" right now, since I wanted to come up with a
performant way of doing it.  Ideas include:

(1) Just re-resolve everything after the first changed sibling.  Could result
in bad slowness in pages as a result, but then again, people chaining these
selectors are kind of asking  for it. ;)

(2) Waste more memory and hold a maximum sibling chain count in the
RenderStyles.  This count would enable you to only re-resolve as many siblings
as necessary on a change.  Would be faster but RenderStyles would have to grow
(making all pages take up more memory).

I'm inclined to just do (1) and not worry about the performance.
