### What?

Related with WEB-669 and initial support for
[WEB-670](https://linear.app/vercel/issue/WEB-670), allows to consume
compiler.emotion with latest turbopack.

I was trying to make additional changes to make test fully pass, but
there are some other failures around so this change cannot able to pass
existing tests yet.
