   7      This test verifies that we reconstruct frames as necessary, after content
   8      (including whitespace & spans) is dynamically inserted as a child of a
   9      flexbox.  (Note that in cases where we know the whitespace is going to be
  10      dropped, we don't bother reconstructing frames. This test is to be sure we
  11      aren't overzealous with that optimization.)
