"justifyContent: space-evenly" gets prefixed to an invalid result

[TheBosZ]

The result of

{
  justifyContent: 'space-evenly'
}

Gets turned into

{
  WebkitBoxPack: "space-evenly",
  justifyContent: "space-evenly"
}

"-webkit-box-pack" doesn't allow the value of "space-evenly": https://developer.mozilla.org/en-US/docs/Web/CSS/box-pack

Hmm. As the value doesn't exist in general, what would you use as a fallback value? We can add justify as well. Otherwise it simply doesn't matter as the browser won't be able to do anything with that invalid value.

Personally, I think it should be dropped as a "prefixed" style since -webkit-box-pack is not directly compatible with justify-content.

It's not a huge deal, I just noticed it when Webstorm marked it as an error in my generated stylesheet.
