Confusing about Entity example

[JayMeDotDot]

I'm new to gpui_kit, so when I read the docs, some examples confused me.

In the official docs, this Entity example seems to express how an Entity notifies an observer that data has been updated.

But because clicking a button causes a re-render, the message displayed in MessagePanel will still be updated, even through I removed _subscription and cx.notify in the this.store.update.

This makes it harder to keep the count at 0.

Maybe changing
let _subscription = cx.observe(&store, |_, _, cx| cx.notify());
to
let _subscription = cx.observe(&store, |_, _, cx| { println!("Notified"); cx.notify() });
will make this much better.
