Unexpected unknown when used with React components and other generic function types

[OliverJAsh]

Filed a TS bug: microsoft/TypeScript#32269

type ComponentType<P> = {
    (p: P): null;
    p?: P;
};

declare const myHoc: <Props>(
    ComposedComponent: ComponentType<Props>,
) => ComponentType<Props>;

declare const Component: (props: {}) => null;

// unknown, expected ComponentType<{}>
const result = pipe(
    () => Component,
    myHoc,
)();
