When using `window.onerror` in the bootstrap script that is hosted in a CDN the error message will show `"Script error."` instead of a proper error message. This is because of the [cross-origin](https://blog.sentry.io/2016/05/17/what-is-script-error/) script. To fix this issue a `crossorigin="anonymous"` attribute needs to be added in the script tag.

Currently, `bootstrapScripts` supports [`src` and `integrity`](https://github.com/facebook/react/blob/0fce6bb498357feb4465859912004b2e20fe7084/packages/react-dom-bindings/src/server/ReactDOMServerFormatConfig.js#L226) as configurations, should it also supports a `crossorigin` property?


const context = React.useContext(inlineLazyServerContextInitialization());
      return <span>{context}</span>;
    }
    await act(() => {
      const {pipe} = renderToPipeableStream(<Foo />);
      pipe(writable);
    });
    expect(getVisibleChildren(container)).toEqual([
      <span>hi this is server</span>,
      <span>hi this is server2</span>,
      <span>hi this is server outer</span>,
      <span>hi this is server outer2</span>,
      <span>default</span>,
    ]);
  });
