  <meta name="assert" content="In this test, the inline size of the orthogonal block is '50%' and its containing block's block size is 'auto'. Since the height of the containing block is indefinite in this test, then the initial containing block's size is used as a fallback which is, in this test, equal to the height of the viewport." />

  <!--

  Inside this batch of 8 sizing-orthog-prct-vrl-in-htb tests:
  001-004: body has 100px margin-bottom and 100px margin-top
  005-008: body has no vertical margins

  Inside each sub-batch of 4 tests:
  001-002: containing block's height is 'auto' therefore indefinite
  003-004: containing block's height is 400px therefore definite

  Inside each sub-sub-batch of 2 tests:
  001: containing block has 1 sentence before and after
  002: containing block has no sentence before and no sentence after

  001 and 005 tests use a 35px thick border.
