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.
