proper serialization of css prop

[havenchyk]

It's mostly a question.

I use jest-styled-components with @testing-library/react and snapshots are looking really cool, but I didn't find a way to serialize css prop of styled-components in snapshots, so it looks ugly with css='...' in snapshots as well.

Is it possible at all to have serialized css somehow better like it's done for classes?

Interesting, I do not get the css prop styles in the snapshot at all on styled components: #250
