failing test case
"justify-content: space-evenly" is implemented for grid layout, but not for flexbox, where instead it behaves as flex-start.
However, since it parses correctly, it is not possible to use the cascade (or @supports) fallback on some other value, making something like this unusable:
justify-content: space-around; /* fallback if the next line is not supported */
Ideally, space-evenly should be implemented in full for flexbox as well (mozilla already has it), but if that's too consuming for a quick fix, as a stop gap measure, using its default fallback alignment (center) would be much better than flex-start. Using space-around would probably be OK as well, as these two values are somewhat close.
I've attached a test-case (also submitted to wpt https://github.com/w3c/web-platform-tests/pull/5336) that currently fails, and would pass if either a full implementation was done, or if a fallback to either center or space-around was implemented instead.

Remove the apostrophe in it's. Shouldn't be there.
