Covid.view.MainContainerController: applySummaryData() => vdom access

    applySummaryData(data) {
        let me        = this,
            container = me.getReference('total-stats'),
            {vdom}    = container;

        me.summaryData = data;

        vdom.cn[0].cn[1].html = Util.formatNumber({value: data.cases});
        vdom.cn[1].cn[1].html = Util.formatNumber({value: data.active});
        vdom.cn[2].cn[1].html = Util.formatNumber({value: data.recovered});
        vdom.cn[3].cn[1].html = Util.formatNumber({value: data.deaths});

        container.update();
        // ...
    }

this logic can no longer work in neo v8 => vdom.cn[0] => {componentId: 'neo-component-2'}

we either need to aggregate the vdom tree or access the child cmps directly to update in parallel.
