Yeah, you likely just want to pay attention to in-flow geometry, which
isn't affected by relpos.  This can overlap if you're doing weird
things, but we can't avoid everything.

Regarding floats, I think we should probably treat them like we do
with a page break that intersects a float, and just remove content
from the float the same way we remove it from the in-flow blocks.
