<!-- This has to be a row flexbox whose item stretches and has vertical writing
mode to trigger:
* a cross size is needed to determine the main size (row flexbox's cross size
is vertical, which is the item's inline size because it has a vertical
writing mode)
* the flex item’s cross size is [...] not definite (if the item didn't
stretch, the definiteness of the container's cross size wouldn't matter
because the cross size would never be definite and the item would always get
fit-content)
-->
<p>Test passes if there is a filled green square.</p>
