2420	error_page directive has no effect on 408	quentin.wentzler.klaxit.com@…		"error_page does not override 408 status code.

With the following server configuration:

{{{
server {
        listen       8080;
        server_name  localhost;

	error_page 400 408 = @convert;

        location @convert {
            return 200;
        }
        
        location = /test_400 {
            return 400;
        }

	 location = /test_408 {
	     return 408;
	 }
    }
}}}

A curl on test_400 reply with a 200:

{{{
curl localhost:8080/test_400 -v
*   Trying 127.0.0.1:8080...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET /test_400 HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.79.1
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< Server: nginx/1.23.1

< Content-Type: application/octet-stream
< Content-Length: 0
< Connection: close
< 
* Closing connection 0
}}}

But on test_408 the 408 is not caught and the connection is closed without response:

{{{
curl localhost:8080/test_408 -v
*   Trying 127.0.0.1:8080...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET /test_408 HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.79.1
> Accept: */*
> 
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server
}}}

[http://nginx.org/en/docs/http/ngx_http_core_module.html#error_page The documentation] does not indicate any special behaviour for this specific status code 

Is this a bug or an issue in the documentation?
