Hi @fiantsev

Thank you for reporting this bug.

Workaround:
Manually redraw halo after chart's redraw: http://jsfiddle.net/BlackLabel/ouzrwtxz/4/

  chart: {
    type: 'pie',
    events: {
      redraw: function() {
        Highcharts.each(this.series, function(s) {
          if (s.halo && s.points && s.points[0] && s.points[0].haloPath) {
            s.halo.attr({
              d: s.points[0].haloPath(0)
            });
          }
        });
      }
    }
  },

Internal note:
Regression since 61a4811 - previously we removed the halo, now it's animated to a path and never updated on redraw.

It appears prior to v6.0.4 too.
