Highcharts Chrome 71 leak - highcharts

Question

When you update from Chrome 70 to 71, addPoint seems to break. There is something in that method that is causing the page to halt and CPU use to skyrocket.
Does not happen on Chrome 70 but does on 71.

Clock "Add Points" and watch your Chrome task manager.
Anyone else seeing this?
var chart = Highcharts.chart('container', {
series: [{
name: 'USD to EUR',
data: []
}]
});
$('#button').click(function () {
var datapts = [];
for(var x=0; x<613645; x++) {
datapts.push([1417410061000+x, x]);
}
for (var i=0; i < datapts.length; i += 1) {
chart.series[0].addPoint(datapts[i], false);
}
chart.redraw();
});

We have concluded this is an error in Chrome 71 rather than highcharts. With a simple jsfiddle using Array splice, this happens even without Highcharts.

If you are having this issue, use setData and not addPoint as setData does not use Array.prototype.splice.
