map.clearOverlays() 无法清理多个RichMarker

var map = new BMapGL.Map("container");

    myRichMarker2 = new BMapGLLib.RichMarker(html2, new BMapGL.Point(116.402922, 39.99908), {

});

// 测试代码
map.addEventListener('click',(e)=>{
// map.clearOverlays() 该清理方法只能清理一个marker ,原因不明

// 清除多个只能手动一个一个清理
const overlays=map.getOverlays()
console.log(overlays)
overlays.forEach(overlay=>{
map.removeOverlay(overlay)
})

})

确实存在这个问题，用了你的解决方案。但是defaultContent依然不清楚。还手动清楚一下
document.querySelectorAll("#platform > div:nth-child(2) > div:nth-child(1) > div").forEach(ele=>{
ele.remove()
})
路书会有一些问题。

可以保存返回的实例，然后挨个清除，他这个估计是没保留返回的overlay实例导致的问题
