LibWeb: Include floats in height:auto for BFC root with inline children

BFC roots with children_are_inline()==true can still have floating boxes
as well. children_are_inline() is only concerned with in-flow children.

For this reason, we have to always consider floats when calculating
height:auto for BFC roots.
