Highmaps mappie zooming issue

I'm trying to adapt my code with the newer version of highcharts/highmaps and I have a problem with map & mappie renderer. The render I need is similar to your demo here : https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/maps/demo/map-pies

For the moment I need to keep my non TOPOJson maps and adapt my existing code with the newer library. The result is here : https://jsfiddle.net/vegaelce/bzy4xgm1/ It's working excepting when you zoom in/out. The pies get more and more smaller when zooming in.

From the existing code I've added the following code

init: function () {
        Highcharts.Series.prototype.init.apply(this, arguments);
        // Respond to zooming and dragging the base map
        Highcharts.addEvent(this.chart.mapView, 'afterSetView', () => {
            this.isDirty = true;
        });
    },
    render: function () {
        const series = this,
            chart = series.chart,
            linkedSeries = chart.get(series.options.linkedMap);
        Highcharts.seriesTypes.pie.prototype.render.apply(
            series,
            arguments
        );
        if (series.group && linkedSeries && linkedSeries.is('map')) {
            series.group.add(linkedSeries.group);
        }
    },

and updated the following

const zoomFactor = chart.mapView.zoom / chart.mapView.minZoom;

What I need is pies don't be affected by zoom level. Can you indicates me how to do that please?

Removing the zoomFactor property makes that pies are not affected by zoom level.
