     // a soft page or column break, rather than setting a pagination strut on itself it normally
     // propagates the strut to its containing block (|this|), as long as our implementation can
     // handle it. The idea is that we want to push the entire object to the next page or column
     // along with the child content that caused the break, instead of leaving unusable space at the
     // beginning of the object at the end of one column or page and just push the first line or
     // block to the next column or page. That would waste space in the container for no good
     // reason, and it would also be a spec violation, since there is no break opportunity defined
     // between the content logical top of an object and its first child or line (only *between*
     // blocks or lines).
