Looking through the list at
<https://www.w3.org/Style/Group/all-properties> (and ignoring obsolete
drafts), I'm getting the following properties with "global" effects:

* counter-increment and counter-set (counter-reset on descendants is
fine, because its effects are scoped already)
* bookmark-*
* break-* (or does BFC contain this?)
* orphans, widows (again, does BFC contain this?)
* flow-from and flow-into
* I think the element becoming a BFC means that 'direction' is fine.
* page-group
* string-set

I believe this is everything.
