| <meta name=assert content="Flex items with layout containment are treated as having no baseline, for that reason their baseline is synthesized from the flex item's border box when they're baseline aligned."> |

| #flex { |
| display: inline-flex; |
| align-items: baseline; |
| background: red; |
| } |
