When trying to use negative styles, the version evaluated in production builds is not correct.

For example with the following code:

const Container = styled.div`
  ${tw`-m-4`}
`

This would evaluate in development development to this:

"marginTop": "-" + _tailwind32.default.negativeMargin["4"]

However in production, it created

"marginTop": "\"-\"+1rem"

Here is chrome not liking the built style in prod
