Prerender dependencies are written multiple times

[Rich-Harris]

Describe the bug

If two pages are prerendered, and both pages request the same file, that file will be written to the output directory twice. If building with svelte-kit build --verbose, it will be logged twice.

Isn't this to be closed as now the build is managed by vite?
