sw: fix mysterious layout loop in CppunitTest_sw_uiwriter3 testTdf104649

This didn't happen with master from a week ago on Fedora 35, but happens
with Monday's master on Fedora 36. Also happens with libreoffice-7-3
branch.

Fundamentally the problem with the bugdoc is that there are tables in
footnotes, which aren't really supported and can't split across pages
like they would need to.

The loop happens because a footnote on page 48 invalidates position of
its anchor frame 549 on page 45.

This is probably pointless, let's only invalidate if the anchor is on
the same page (it should be on the same page, but probably the tables in
other footnotes get in the way).
