<!-- Testcase to ensure we handle ::before and ::after pseudo-elements on a
     flex container, specifically when they've got display:table-row or
     table-cell.

     The table-row / table-cell 'display' values should be blockified, and the
     pseudo-elements should be treated as flex items. (They should not get
     wrapped in an anonymous table box.) -->
