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