highcharts sunburst datalabels not showing after drilldown or drillup

Question

The highcharts sunburst chart is great, but it doesn't show the dataLabels after you drilldown or drillup

This is the stock example: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/sunburst/

Notice that once you drilldown to a continent or area, the datalabels disappear. I noticed that there is a note in the github submits, is this fixable? https://github.com/highcharts/highcharts/commit/3ffa39287f4b713517200d7c0b1d498c392c4fba

I can make them re-appear by changing the data source (using setData), but this should happen automatically. I have tried to chart.redraw, as well as the event.drilldown but no joy

series: [{
    type: "sunburst",
    data: data,
    allowDrillToNode: true,
    cursor: 'pointer',
    dataLabels: {
        /**
         * A custom formatter that returns the name only if the inner arc
         * is longer than a certain pixel size, so the shape has place for
         * the label.
         */
        formatter: function () {
            var shape = this.point.node.shapeArgs;

            var innerArcFraction = (shape.end - shape.start) / (2 * Math.PI);
            var perimeter = 2 * Math.PI * shape.innerR;

            var innerArcPixels = innerArcFraction * perimeter;

            if (innerArcPixels > 16) {
                return this.point.name;
            }
        }
  }]

You can report it as a bug here: https://github.com/highcharts/highcharts/issues. As for the workaround for now, you can call `setSize` function without arguments on point click event. Example: http://jsfiddle.net/h36L18or/. — pawel_d, Oct 27 '17 at 14:50
Thanks d_paul so this is forcing the labels to redraw by triggering setSize on the point click event? How would I achieve the same workaround on a drill up? — user1758908, Oct 28 '17 at 16:15
apologies @d_paul, the drillup does partially work: if I click on the chart center to drillup the labels are redrawn, but if I click on the drillup box (top right), the labels still don't show — user1758908, Oct 30 '17 at 15:35
