  <title>CSS Writing Modes Test: sizing of orthogonal 'horizontal-tb' block with 'auto' inline size inside definite-sized 'vertical-lr' containing block</title>

  <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 width (inline-size) of the containing block is definite in this test, then the constrain is the width (inline-size) of such containing block which is, in this test, 400px. But the min-content inline size of the orthogonal block is greater than the width (inline-size) of the containing block. Therefore, the min-content inline-size will become the width of the orthogonal block." />

  <!--

  shrink-to-fit formula 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-htb-in-vlr tests:
  001-012 : body has 100px margin-left and 100px margin-right
  013-024 : body has no horizontal margins

  Inside each sub-batch of 12 tests:
  001-006: containing block's width is 'auto' therefore indefinite
  007-012: containing block's width 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 width is 'auto'
  002: orthogonal block's width is 'auto' and its min-content
  inline size (1 very long word) is wider than constraint
  003: orthogonal block's width is 'auto' its max-content inline-size
  is narrower than max(min-content, constraint)
