Description
Describe the bug
Hi team,
Wanted to test the new version but it's not playing well with type-fest JsonValue. Not sure why.
Reproduction
import type { JsonValue } from 'type-fest';
it('should succeed', async () => {
const a = {} as JsonValue;
const b = {} as JsonValue;
expect(a).toStrictEqual(b);
});rror TS2589: Type instantiation is excessively deep and possibly infinite.
44 expect(a).toStrictEqual(b);
