jest.mock does not work on .tsx files

[flunderpero]

First of all, it is great that you found a workaround to make jest.mock work at all! (I originally opened evanw/esbuild#412)

That being said, it does not seem to work with .tsx files. I am getting this error:

    SyntaxError: test.spec.tsx: Unexpected token, expected "," (37:37)

    > 37 |         const sut = render(<LinkCard card={card} />)

I see you use babel-jest under the hood. Perhaps it is just a case of a missing plugin or configuration option (I am not familiar with babel at all).
