Existing specs often fail to take account of the one-to-many relationship
of elements and boxes, and have had lots of ambiguities as a result, so
existing spec text is often not a good model to follow :-(. Some specs do
take account of multiple boxes where the problems became glaringly obvious
and editors were responsive, e.g. CSSOM View discusses multiple boxes in a
few places.

I don't think we should try to have the Fragmentation spec define how every
other spec should be modified to handle elements with multiple boxes. There
isn't a uniform way to do those modifications, so it would violate spec
modularity and make things very hard to understand since you'd constantly
be referring to CSS Fragmentation to understand how each spec actually
needs to work. E.g., I think Flexbox spec, not the Fragmentation spec,
should define any differences between pagination of flexboxes and other
kinds of boxes, and it should define how flexbox features should work in
the presence of pagination.
