lock is 'auto' and its containing block's block size is also 'auto'. Since the h

| 21 shrink-to-fit formula is: min(max-content, max(min-content, constraint)) |
| 22 |
| 23 max-content inline size: narrowest inline size needed to fit its contents |
| 24 if none of the soft wrap opportunities within the box were taken. Eg: |
| 25 max-content of "I am a text sentence." is "I am a text sen
tence." |
| 26 https://www.w3.org/TR/css-sizing-3/#max-content-inline-size |
| 27 |
| 28 min-content inline size of the box: longest word in a sentence or longest non-
breakable |
| 29 inline box (inline replaced or inline-block). Eg: min-content of "I am a text
sentence." |
| 30 is "sentence." |
| 31 https://www.w3.org/TR/css-sizing-3/#min-content-inline-size |
| 32 |
| 33 contraint: min(available space, initial containing block's size) |
| 34 |
| 35 available space: this is either a measurement of its containing block |
| 36 (if that is definite) or an infinite size (when it is indefinite). |

| 41 Inside this batch of 24 sizing-orthog-vrl-in-htb tests: |
| 42 001-012: body has 100px margin-top and 100px margin-bottom |
| 43 013-024: body has no vertical margins |
| 44 |
| 45 Inside each sub-batch of 12 tests: |
| 46 001-006: containing block's height is 'auto' therefore indefinite |
| 47 007-012: containing block's height is 400px therefore definite |
| 48 |
| 49 Inside each sub-sub-batch of 6 tests: |
| 50 001-003: containing block has 1 sentence before and after |
| 51 004-006: containing block has no sentence before and no sentence after |
| 52 |
| 53 Inside each sub-sub-sub-batch of 3 tests: |
| 54 001: orthogonal block's height is 'auto' |
| 55 002: orthogonal block's height is 'auto' and its min-content |
| 56 inline size is greater than containing-block's (definite) height (1 very long
word) |
| 57 003: orthogonal block's height is 'auto' and its max-content inline size |
| 58 is smaller than containing-block's height (short sentence) |
