Should compile fine.

Types of property 'setState' are incompatible. Type '{ <K extends never>(f: (prevState: {}, props: {}) => Pick<{}, K>, callback?: (() => any) | undefi...' is not assignable to type '{ <K extends keyof S>(f: (prevState: S, props: P) => Pick<S, K>, callback?: (() => any) | undefin...'. Types of parameters 'f' and 'f' are incompatible. Types of parameters 'prevState' and 'prevState' are incompatible. Type '{}' is not assignable to type 'S'.
