Well, you can in some circumstances.  ^_^

What you need to, Thaddee, is figure out what browsers do when, for
example, an inline is broken around a large float, or a block is
broken across multicol columns.  The usual answers are that they
either care about (1) the (border) box of the first fragment, or (2)
the bounding box containing all the fragments.
