请问如何给StyleSetter设置默认值?

复现截图

想给StyleSetter直接设置默认值，目前碰到一些问题，用snippets的方式，直接给style赋值是可以的，但是界面里面的占位视图会消失， 查询源码得到，这里对style有做判断，如果不为空，就直接不显示占位视图，请问这样做是为什么？那我如何能给StyleSetter设置默认值，并且保留占位视图?

 {
          "componentName": "Column",
          "library": "LYMaterials",
          "title": "Column",
          "icon": "",
          "snippets": [
            {
              "title": "Column",
              "schema": {
                "componentName": "Column",
                "title": "Column",
                "props": {
                  "style": {
                    "display": "flex",
                    "flexDirection": "column"
                  }
                }
              }
            }
          ]
        },

这里有做判断 https://github.com/alibaba/lowcode-engine/blob/main/packages/react-simulator-renderer/src/renderer-view.tsx#L205

可以通过在设计视图里，自定义占位符实现~

class YourComponent {
  render() {
    if (this.props.leaf.isEmpty) {
      return <div>空</div>;
    }
    return 其他视图;
  }
}
