| CSS Test: Testing that used "flex-basis: content" is treated as |

| <!-- The idea of this test is to be sure the UA is using the "max-content" size |
| (and not e.g. the "fit-content size") when resolving the flex base size |
| inside each flex container. To differentiate between max-content and |
| other intrinsic size possibilities (min-content/fit-content), we: |
| - use flex items with a large difference between its min-content size & |
| its max-content size (e.g. wrappable content). |
| - use a very small container (to compress the size, if the UA incorrectly |
| allows the size to be influenced by the container size). |
