  <meta name="assert" content="In this test, the inline size of the orthogonal block is 'auto' and its containing block's block size is '400px'. Since the height of the containing block is definite in this test, then constrain is the height of such containing block which is, in this test, 400px. This test presumes that the initial containing block's height is greater than 400px. In this test, the max-content will be smaller than the height of the containing block. Therefore the inline size of div#ortho-block-vrl will be its max-content." />

  <!--

  shrink-to-fit formula is: min(max-content, max(min-content, constraint))

  max-content inline size: narrowest inline size needed to fit its contents
  if none of the soft wrap opportunities within the box were taken. Eg:
  max-content of "I am a text sentence." is "I&nbsp;am&nbsp;a&nbsp;text&nbsp;sentence."
  https://www.w3.org/TR/css-sizing-3/#max-content-inline-size

  min-content inline size of the box: longest word in a sentence or longest non-breakable
  inline box (inline replaced or inline-block). Eg: min-content of "I am a text sentence."
  is "sentence."
  https://www.w3.org/TR/css-sizing-3/#min-content-inline-size

  contraint: min(available space, initial containing block's size)

  available space: this is either a measurement of its containing block
  (if that is definite) or an infinite size (when it is indefinite).

  Inside this batch of 24 sizing-orthog-vrl-in-htb tests:
  001-012: body has 100px margin-top and 100px margin-bottom
  013-024: body has no vertical margins

  Inside each sub-batch of 12 tests:
  001-006: containing block's height is 'auto' therefore indefinite
  007-012: containing block's height is 400px therefore definite

  Inside each sub-sub-batch of 6 tests:
  001-003: containing block has 1 sentence before and after
  004-006: containing block has no sentence before and no sentence after

  Inside each sub-sub-sub-batch of 3 tests:
  001: orthogonal block's height is 'auto'
  002: orthogonal block's height is 'auto' and its min-content
  inline size is greater than containing-block's (definite) height (1 very long word)
  003: orthogonal block's height is 'auto' and its max-content inline size
  is smaller than containing-block's height (short sentence)
