Code highlighting breaks when using return with text content

[LsHallo]

Describe the bug Code highlighting breaks when using return with text content.

To Reproduce Paste this config:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    location / {
        add_header Content-Type "text/plain";
        return 200 "LB";
    }

    location ~ ^(.*)\.rss {
        resolver 127.0.0.11 ipv6=off;
        rewrite ^ $request_uri break;
        return 400;
        proxy_pass http://nginx_target$uri;
    }
}

Code highlighting breaks after the return 200 "LB" block:

Expected behavior Code highlighting will continue to work further down in the config file.

it isn't the return I believe it's the quotes that cause this; not sure why
