Description
## **Describe the bug (required)** / **详细描述 bug（必填）**
在spa项目中,把预览组件Preview 放在某个路由下， 切换路由后回来会把相同js和css资源重新放入head标签中，这样就会无限叠加，
目前能想到的就是assetLoader.load的时候判断head已经有相同的link和script就不引入，但是componentName为page的css每次会自动引入，css传空也会引入，是否已经有其他的优化方案了。

Research direction
Start by reproducing the Preview component in an SPA, navigating away, and returning to its route while inspecting the document head. Trace assetLoader.load and the componentName=page CSS handling; done means repeated navigation no longer appends duplicate JavaScript or CSS resources, including when the CSS value is empty.
