[@rollup/plugin-typescript] Doesn't parse packages outside root dir, monorepo packages

Rollup Version

3.25.1

Operating System (or Browser)

Browser

Node Version (if applicable)

16.14.2

Link To Reproduction

https://stackblitz.com/edit/stackblitz-starters-tyztyr?file=packages%2Fmy-package-with-rollup%2Frollup.config.mjs

Reproduction Steps

1. Open https://stackblitz.com/edit/stackblitz-starters-tyztyr?file=packages%2Fmy-package-with-rollup%2Frollup.config.mjs
2. Run cd packages/my-package-with-rollup/
3. Run npm run build

Expected Behaviour

Using the @rollup/plugin-typescript plugin in conjunction with the @rollup/plugin-node-resolve plugin should allow rollup to parse TypeScript in files outside the main directory:

// rollup.config.mjs
import nodeResolve from '@rollup/plugin-node-resolve';
import typescript from '@rollup/plugin-typescript';

export default {
  input: ['index.ts'],
  output: {
    file: 'bundle.js',
    format: 'esm',
  },
  plugins: [nodeResolve(), typescript()],
};

// package.json
...
 "dependencies": {
    "my-workspace-package": "workspace:^"
  }

Actual Behaviour

Rollup errors: [!] RollupError: Unexpected token (Note that you need plugins to import files that are not JavaScript).

Including outside files in the include pattern does nothing as well:

typescript({ include: ['index.ts', '../my-workspace-package/index.ts'] }),

The filterRoot set to false also doesn't fix it, which I would expect it to based on the docs:

typescript({ filterRoot: flase })
