setting selector is ineffective

[smanalysis]

My server is Artemis 2.16, and js code is:

<script>
    $(document).ready(function() {
        let client = Stomp.client("ws://127.0.0.1:61613");
        // this allows to display debug logs directly on the web page
        client.debug = function (str) {
            console.log(str);
        };
        // the client is notified when it is connected to the server.
        // let headers = {"ack": "client", "selector": "location = 'Europe'"};
        let connected = function(frame) {
            client.subscribe("/test", function(message) {
                $("#messages").append("<p>" + message.body + "</p>\n");
            }, {"durable-subscription-name": "filter", "selector": "tag = 'aaa'"});
        };
        client.connect({"client-id": "abc"}, connected);
    });
</script>

but the setting of selector is ineffective (connection and subscribe is correct), the client can receive message with other tags, such as bbb . The debug output is:
