<title>CSS Writing Modes Test: sizing of orthogonal 'horizontal-tb' block with 'auto' inline size inside definite-sized 'vertical-rl' 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'. In this test, the max-content inline size of the orthogonal block will be smaller than the width of its containing block. Therefore the inline size of div#ortho-block-htb will be its max-content inline-size." />
<!--
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 am a text 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-vrl 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' and its max-content inline size
is narrower than max(min-content, constraint)
