Velocity doesn't seem to forward server address to backend servers?

[ThrowerWay]

 @EventHandler
    public void onPlayerHandshake(PlayerHandshakeEvent event) {
        if (event.getServerHostname() != null) {
            hostNames.put(event.getUniqueId(), event.getServerHostname().toLowerCase().replace(" ", ""));
        }
    }

This code worked on bungee but doesn't on velocity, I have modern forwarding enabled and paper backend

[Shane Freeder]

the forwarding mechansim is irrelevant

for RegisteredServer#ping(), we pass through the hostname as defined in the servers list, for an actual player, we try to pass through the players vhost that they sent us (else, we fall back to the registered server info if we don't have that)
