Corrected.

Corrected.

That's right, and I don't know a way around it either.

I hope so. This is on my list under the general notion of
cross-references. They may refer to counters, but also to page numbers
("see equation 6 on page 23" or "see equation 6 on this page")

But as you note, this is probably not just a CSS issue: it needs some
markup.
