| <!-- This test exists for symmetry with the previous set of tests |
| (flexbox-flex-basis-content-003*). Those previous tests check how |
| "flex-basis:content" is resolved to a flex base size, in the inline axis, |
| when the container's size is constrained in that axis. This test does the |
| same, but for the *block* axis, using flex-direction:column. As with the |
| previous set of tests, the expectation here is that we should use the |
| item's max-content size as its flex base size. Note that there's a bit |
| less subtlety here because intrinsic sizes (min-content, max-content) are |
| typically all the same in the block axis. |
