Websocket.next endpoint throwing exception on opening of connection doesn't increment count of quarkus_websockets_server_connections_opened_errors_total{uri=${ENDPOINT}} metric counter.

For example, I have a following websocket:

@WebSocket(path = "/failing")
public class FailingWebsocket {
    @OnOpen()
    public void onOpen() {
        throw new RuntimeException("Websocket failed to open");
    }
.
.
.
}

But opening a connection on it doesn't increment the counter. Same happens for the quarkus_websockets_client_connections_opened_errors_total{uri=${ENDPOINT}} counter.
