        active: true,
    },
    autoLog: {
        on: () => autorun(() => console.log(toJS(ob))),
        // disposer pattern like mobx autorun/reaction does not require off function.
        active: false,
        // active: false will not automatically run at first.
    }

setTimeout(() => {
    lOb.state.trackScroll.active = true; // restart trackscroll 1s later.
