So, I've been thinking about this, and I think we should resolve
this conflict in favor of the Pagination section, because that's
what we'll have to do for Grid Layout.

In Grid Layout, if you set page-break-before on an item, it
will have to push the whole row because there's no such thing
as wrapping.

(Obviously we'd thought this through before, when we were writing
the Pagination section, but I couldn't remember the logic.)

I'll clarify the spec.
