## 问题内容
DivGraphic构造时的clampToGround生效，调用setOptions()或者setStyle()时，clampToGround贴地设置未生效。

## 重现步骤
```
function addDemoGraphic1(graphicLayer) {
    let options1 = {
        position: [116.741611, 31.408068, 1000],
        style: {
            html: `<div class="marsBlackPanel  animation-spaceInDown">
              <div class="marsBlackPanel-text">大湖名城,创新高地1</div>
          </div>`,
            horizontalOrigin: Cesium.HorizontalOrigin.LEFT,
            verticalOrigin: Cesium.VerticalOrigin.CENTER,
            clampToGround: true,
            // 高亮时的样式
            highlight: {
                // type: mars3d.EventType.click,
                className: "marsBlackPanel-highlight"
            }
        },
        attr: { remark: "示例1" }
    }
    let options2 = {
        position: [116.793611, 31.458068, 1000],
        style: {
            html: `<div class="marsBlackPanel  animation-spaceInDown">
              <div class="marsBlackPanel-text">大湖名城,创新高地2</div>
          </div>`,
            horizontalOrigin: Cesium.HorizontalOrigin.LEFT,
            verticalOrigin: Cesium.VerticalOrigin.CENTER,
            clampToGround: true,
            // 高亮时的样式
            highlight: {
                // type: mars3d.EventType.click,
                className: "marsBlackPanel-highlight"
            }
        },
        attr: { remark: "示例2" }
    }

const graphic1 = new mars3d.graphic.DivGraphic(options1)
    graphicLayer.addGraphic(graphic1)

setTimeout(() => {
        graphic1.setOptions(options2)
    }, 5000)

const graphic2 = new mars3d.graphic.DivGraphic(options2)
    graphicLayer.addGraphic(graphic2)
}

```

## 实际结果
更新options后或者更新style后的DivGraphic没有贴地。

## 期望结果
期望setOptions或者setStyle修改贴地时，和创建带高度的DivGraphic的逻辑一致，设置clampToGround生效
