Nginx Cross-origin fails when both cross-origin and cache policies are used at the same time

Question

Below is my nginx configuration file.

server {

    listen       80;
    server_name  test.abc.com;

    location / {
        if ($request_filename ~* .*\.(?:htm|html)$) {
            add_header Cache-Control "private, no-store, no-cache, must-revalidate, proxy-revalidate";
        }
        add_header 'Access-Control-Allow-Origin' 'https://test.abc.com';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Credentials' true;
        add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
        if ($request_method = 'OPTIONS') {
            return 204;
        }

        root /etc/nginx/html/test/;
        index index.html;
        try_files $uri $uri/ /index.html;
    }
}

But the cross-domain related configuration is lost in the response header.
