Flow + React + Props: Assigning a class type to parameter does not resolve the props

Hi

When using the following code the TestComponent does not resolve the props from A. When I use A directly it works as expected. Is there something wrong from my side?

// @flow
import React, {Component} from 'react';

type AType = {
  myProp1: string,
  myProp2: string,
};

class A extends Component<AType> {
  props: AType;
}

type BType = {
  myProp1: string,
  myProp2: string,
};

function myRender(TestComponent: A): Component {
  class B extends Component<BType> {
    render(): Component {
      return <TestComponent />;
      // return <A />;
    }
  }

  return B;
}

myRender(A);
