Need a deep layout pass when becoming (un)fragmented.

When an object ceases to be fragmented (e.g. when leaving print preview), there
may be pagination struts that need to be removed. Therefore, we need to lay out
all descendants of a block that ceased to establish a fragmentation context.

Similarly, when becoming fragmented (e.g. when entering print preview), we need
to go through every descendant. There may both be implicit and forced breaks to
insert.
