    7.0-22 Web Container adds zabbix-server as 127.0.0.1 to /etc/hosts

    Zabbix 7.0.22 web container, when starting, has the hostname of the zabbix server added to /etc/hosts 127.0.0.1 entry, although it's resolvable through DNS.
    Looked at the container environment vars for both server/web, but can't figure out why it's happening.

    It breaks the "zabbix server is running" check, but zabbix-server is running fine in another container, in the same docker network, on the same host. Agent2 is installed at the host level.

    My workaround is to remove it from the frontend /etc/hosts container.

    Idea's welcome.
