Description
chart.on("datazoom", () => {
const opt = chart.getOption();
// TODO： 需要重新设置一些配置项
chart.setOption(opt);
)}
使用的Skiachart，监听datazoom的时候重新设置option会引起datazoom的闪烁，而且拖动时datazoom的折线数据不可见，拖动结束后调用这个监听重新setOption才可以使datazoom的折线出现，但是会闪一下，包括左右的handleIcon也会闪一下。
请问下应该怎么解决这个问题？ @zhiqingchen

Research direction
Reproduce the issue with the shown chart.on("datazoom") handler and chart.getOption()/setOption() calls in a Skia-backed chart. Investigate the datazoom rendering during dragging, including the line data and handleIcon, and confirm the fix prevents flicker while keeping both visible before, during, and after the drag.
