Don't let outer multicol height confuse orphans/widows on inner multicol.

In the initial layout pass of a multicol container with auto height,
there'll be no known breaks, but we will honor the contraints of any
outer fragmentation context, and insert pagination struts if necessary.
These pagination struts need to be ignored when we calculate the height
requirements imposed by orphans and widows requirements, or we risk
making the inner multicol too tall.
