With this:

```js
    const Add = React.memo(props => {
      return props.inner + props.outer;
    });
    Add.defaultProps = {
      inner: 2,
    };
    const LazyAdd = lazy(() => fakeImport(Add));
```

If I render `LazyAdd` again after it resolves, it won't get the `inner` default prop value. This is a bug.
ReactTestRenderer.unstable_yield(
          `UNSAFE_componentWillUpdate: ${this.props.text} -> ${nextProps.text}`,
        );
      }
      UNSAFE_componentWillReceiveProps(nextProps) {
        ReactTestRenderer.unstable_yield(
          `UNSAFE_componentWillReceiveProps: ${this.props.text} -> ${
            nextProps.text
          }`,
        );
      }
      render() {
        return <Text text={this.props.text + this.props.num} />;
      }
    }
    const LazyClass = lazy(() => fakeImport(C));
    const root = ReactTestRenderer.create(
      <Suspense fallback={<Text text="Loading..." />}>
        <LazyClass num={1} />
      </Suspense>,
    );
    expect(ReactTestRenderer).toHaveYielded(['Loading...']);
    expect(root).toFlushAndYield([]);
    expect(root).toMatchRenderedOutput('Loading...');
    await Promise.resolve();
    root.update(
