Is an EventSource (SSE) supposed to try to reconnect indefinitely?

Question

I\'m working on a project utilizing Server-Sent-Events and have just run into something interesting: connection loss is handled differently between Chrome and Firefox.

here's another variation folks might like

let events = null;

function connect() {
    events = new EventSource("/some/url");
    events.onerror = function() {
        events.close();
    }
}
connect();

let reconnecting = false;
setInterval(() => {
    if (events.readyState == EventSource.CLOSED) {
        reconnecting = true;
        console.log("reconnecting...");
        connect();
    } else if (reconnecting) {
        reconnecting = false
        console.log("reconnected!");
    }
}, 3000);
