Workaround:

Replace current poximate positions:

(function(H) {
  H.Legend.prototype.proximatePositions = function() {
    var chart = this.chart,
      boxes = [],
      alignLeft = this.options.align === 'left';

    H.each(this.allItems, function(item) {
      var lastPoint,
        height,
        useFirstPoint = alignLeft;

      if (item.xAxis && item.points) {

        if (item.xAxis.options.reversed) {
          useFirstPoint = !useFirstPoint;
        }
        lastPoint = H.find(
          useFirstPoint ?
          item.points :
          item.points.slice(0).reverse(),
          function(item) {
            return H.isNumber(item.plotY);
          }
        );
        height = item.legendGroup.getBBox().height;
        boxes.push({
          target: item.visible ?
            (lastPoint && lastPoint.plotY || item.xAxis.height) - 0.3 * height : chart.plotHeight, // Fix #8638
          size: height,
          item: item
        });
      }
    }, this);
    H.distribute(boxes, chart.plotHeight);
    H.each(boxes, function(box) {
      box.item._legendItemPos[1] =
        chart.plotTop - chart.spacing[0] + box.pos;
    });

  }
})(Highcharts);
