用泛型返回`typeof`

Question

在打字稿中，如何返回使用泛型的超类的子类？

这就是我希望的工作方式：

interface SuperProps {}

class SuperComponent<P extends SuperProps> extends React.Component<P> { }

interface SubProps extends SuperProps {}

class SubComponent extends SuperComponent<SubProps> { }

function get(): typeof SuperComponent {
    return SubComponent;
}

但是，出现以下错误：

error TS2322: Type 'typeof SubComponent' is not assignable to type 'typeof SuperComponent'.
  Type 'SubComponent' is not assignable to type 'SuperComponent<P>'.
    Types of property 'props' are incompatible.
      Type 'Readonly<{ children?: ReactNode; }> & Readonly<SubProps>' is not assignable to type 'Readonly<{ children?: ReactNode; }> & Readonly<P>'.
        Type 'Readonly<{ children?: ReactNode; }> & Readonly<SubProps>' is not assignable to type 'Readonly<P>'.

这基本上是说SubProps！= P，对吧？我该怎么办？
