<meta name="assert" content="Flex items don't get definite heights just because their specified main sizes are definite. This affects flex items with with a flex-basis that behaves as auto, where the auto-behaving flex-basis derives from omitted flex-basis from flex shorthand." />
<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
<div style="display: flex; flex-direction: column;">
<!-- Remove min-height:auto so we don't have to think about whether it matters. -->
<!-- Chrome 96 and Firefox 94 still use 0% as the value of flex-basis when it is omitted from the flex shorthand, despite the recent spec change that dictates 0px instead of 0%. -->
