机车滚动在大型内联svg上减速

如何解决机车滚动在大型内联svg上减速

我正在使用Locomotive scroll和amcharts绘制svg地图作为固定高度容器的背景。当地图位于视口中时，滚动速度会变慢。
这是我所做的一个粗略示例：https://codepen.io/anastasiavyalt/pen/GRqGraB。
如果您设置显示：无或可见性：隐藏或不透明：0到svg上的css，则滚动行为符合预期，这是我想要实现的。 有什么可以做的吗？

html

<div class="wrapper" data-scroll-container>
    <div data-scroll-section>
        <h1 data-scroll>Loco<br> motive<br> scroll</h1>
    </div>
    <div data-scroll-section>
      <p>

  height: 250vh;
}

#chartdiv {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;

js

const locoScroll = new LocomotiveScroll({
    el: document.querySelector('[data-scroll-container]'),smooth: true
});
am4core.ready(function() {
  var chart = am4core.create("chartdiv",am4maps.MapChart);
  chart.maxZoomLevel = 1;
  chart.geodata = am4geodata_worldLow;
  chart.projection = new am4maps.projections.Miller();
  var polygonSeries = chart.series.push(new am4maps.MappolygonSeries());
  polygonSeries.exclude = ["AQ"];
  polygonSeries.useGeodata = true;
  var polygonTemplate = polygonSeries.mappolygons.template;
  polygonTemplate.tooltipText = "{name}";
  polygonTemplate.polygon.fillOpacity = 0.6;
  var hs = polygonTemplate.states.create("hover");
  hs.properties.fill = chart.colors.getIndex(0);
