When a change happens and the provider is not connected yet and or currently offline, the change is lost.

Describe the solution you'd like

At the moment messages are only sent, when the websocket is available. Otherwise the update is just lost. The API also does not provide any methods to deal with initial connect in a nice way.

I have a react effect that connects to a y-sweet server whenever a ID changes. So it works like this:

React.useEffect(() => {
    const doc = new Y.Doc();
    const provider = createYjsProvider(...);
    init(doc, id);
}, [id]);

But when init is called, the doc is provider is not available yet. Therefore I had to wait for the connection to be established

React.useEffect(() => {
    const doc = new Y.Doc();
    const provider = createYjsProvider(...);
    await new Promise(resolve => {
            const handler = () => {
                if (provider.wsconnected) {
                    resolve(true);
                }
            };

            provider.on('status', handler);
        });
    init(doc, id);
}, [id]);

I think there should be a limited queue to handle this problem or network hiccups.
