Enabling http2 for one server block apparently enables it for other SSL server blocks.
If this is a feature I am not finding the documentation explaining the behaviour anywhere.

Expected: http2 is only enabled for server blocks where http2 is enabled.

Example config:

# redir secure root domain to www
server {
    listen 443 ssl;
    listen [::]:443 ssl;


    ssl_certificate certs/;
    ssl_certificate_key certs/;
    # add -- to middle of hostname to make obvious to test client when we hit this server block
    return 301$request_uri; 

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;


    root /var/www/;

    ssl_certificate certs/;
    ssl_certificate_key certs/;

    # restricted ciphers to support http2

    # ...

curl the redirect server block

$ curl -I
HTTP/2 301
server: nginx
date: Fri, 02 Aug 2019 15:53:01 GMT
content-type: text/html
content-length: 178

Note the response is HTTP/2 even though we are hitting the first server block (we know for sure we are hitting the first server block because of the -- in the redirect (location header).

I would expect this response to be HTTP 1.1 since http2 is not configured for this server block.

Bug or feature?
