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?


formMethod = customFields.method;
      formTarget = customFields.target;
      formData = customFields.data;
    } else {
      
      
      
      
      
      target.push(
        attributeSeparator,
        stringToChunk('formAction'),
        attributeAssign,
        actionJavaScriptURL,
        attributeEnd,
      );
      name = null;
      formAction = null;
      formEncType = null;
      formMethod = null;
      formTarget = null;
      injectFormReplayingRuntime(responseState);
    }
  }
  if (name != null) {
    pushAttribute(target, 'name', name);
  }
  if (formAction != null) {
    pushAttribute(target, 'formAction', formAction);
  }
