Enable CORS when using the AWS API Gateway Request Validator

Question

I install the AWS API Gateway using CORS successfully when the request is valid. I have a 200 status code, as well as CORS headers, which is nice.

But when the AWS API Gateway Request Validator detects invalid input, I have a 400 status code, but CORS headers are not sent ...

This is really unsuccessful because the client sees CORS errors instead of a real 400 error (for example, the fetchclient cannot distinguish 400 errors due to CORS errors).
