VSCode not respecting declaration map without absolute sourceRoot

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: 1.101.2
- OS Version: MacOS 15.1.1

Steps to Reproduce:

1. Clone https://github.com/ishchhabra/pnpm-workspace-example
2. Open `apps/web/src/app/page.tsx` and CMD+Click on `Link`. It'll open the `Link.d.ts` file (from dist).

If I add
`"sourceRoot": "/Volumes/Development/pnpm-workspace-example/packages/ui/src"` to `packages/ui/tsconfig.json`, it takes me to the `Link.tsx` file in `packages/ui/src/components`, however, using `"sourceRoot": "./src"` takes user to the declaration file in `dist/`.

I am able to workaround by adding `"@packages/ui": ["../../packages/ui/src"]` in `paths` in the `tsconfig` for `apps/web`, however that is not ideal since that requires defining paths in every app that uses the package.

Reproduisez la navigation de apps/web/src/app/page.tsx vers Link.d.ts à l’aide de pnpm-workspace-example, puis comparez packages/ui/tsconfig.json avec des valeurs absolues et relatives de sourceRoot. Examinez comment la declaration map est résolue et vérifiez que le paramètre relatif navigue vers packages/ui/src/components/Link.tsx sans per-app paths overrides.
