Title: 🐛 [Bug]: The default value is set to the component but it does not take effect

[chilingling]

@kalvinhu 当前可以使用 snippts 中的代码片段设置默认值：

{
  "snippets": [
    "name": {
        "zh_CN": "Kvn 的柱状图"
      },
      "icon": "button",
      "screenshot": "",
      "snippetName": "KvnBarchart",
      "schema": {
        "props": {
          "width": "600",
          "height": "600"
        }
      }
  ]
}
