React 17 Emotion Build Error

If you use Emotion in React 17, you might find the following problem:

pragma and pragmaFrag cannot be set when runtime is automatic.
> /** @jsx jsx */

TL;DR;

Do this:

/** @jsxRuntime classic */
/** @jsx jsx */

When will it be fixed

Shortly after the upcoming release of TypeScript 4.1
