Functions do not work with arrays

[bigslycat]

It works:

const MyComp = styled('div')({
  border: [2, 'solid', 'white'],
});

This does not work:

const MyComp = styled('div')({
  border: ({ children }) => !children && [2, 'solid', 'white'],
});

Works:

const MyComp = styled('div')({
  border: ({ children }) => !children && ['2px', 'solid', 'white'].join(' '),
});

Thanks for this issue!

It looks like a bug with JSS, see cssinjs/jss#497
