Reviewed by Antti Koivisto.

This is in preparation for static position out-of-flow box computation where the
static (logical) vertical position depends on whether the out-of-flow box has a previous
sibling with content and/or decoration.
(This also addresses the box-decoration case for spanning line boxes.)
