Pagination struts don't update properly when collapsing margin estimates are wrong. It's hard to see this problem without a very small "page" size, so regions are what brought it to my attention. Basically if your logical top estimation is wrong, you need to do a relayout prior to applying final pagination adjustments. In other words, you have to do a 3-pass layout instead of a 2-pass layout, since fixing up your collapsed margin or clearance position may cause you to then propagate new pagination strut information.

Fixing this bug will cause some regions tests to fail. These tests were only passing through sheer luck, though, and the bug exposed by this is already present in regions.
