Describe the bug

In my project, I need to reference a static assets file outside the project root.
See code here:
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/plugins/importAnalysis.ts#L336

It seems that in ssr mode, vite will not prepend base to assets file url
However, code here:
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/plugins/importAnalysis.ts#L523

vite will replace base with ''. WHAT IF my project directory already contains base as part of path? In my project, it will replace it with ''.
For example, my project root directory is like /projects/subpath, setting base in vite.config.ts to '/subpath/', start vite in ssr mode and you will find all the assets reference url is normalized as @fs/projects/assets/xxx.svg rather than @fs/projects/subpath/assets/xxx.svg
