aws-cdk: AWS APIgateway: fromRestApiAttributes does not bring all the RestAPI configuration

Describe the bug

I was following this documentation section, where there’s a workaround for multiple stack describing api gateway resources:

Breaking up Methods and Resources across Stacks It is fairly common for REST APIs with a large number of Resources and Methods to hit the CloudFormation limit of 500 resources per stack.

So I broke my stack in several nested stacks and imported back my api in each nested stack using the ``fromRestApiAttributes``` method. The correct object was found but not all the configuration appeared.

Expected Behavior

I was expecting the full object as set during the API creation in the main stack.

Current Behavior

Dumping the object, I had the following:

{
...
    defaultIntegration: undefined,
    defaultMethodOptions: undefined,
    defaultCorsPreflightOptions: undefined
...
}

instead of:

{
...
    defaultIntegration: undefined,
    defaultMethodOptions: undefined,
    defaultCorsPreflightOptions: { allowOrigins: [Array], allowMethods: [Array] },
...
}

Reproduction Steps

The following piece of code as mentionned in the documentation: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_apigateway-readme.html#breaking-up-methods-and-resources-across-stacks
