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

<!-- 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.
