   cd /tmp/repro
   npm init -y
   npm add typescript@7.0.2
   echo '{}' > tsconfig.json

2. Create files

   // export.ts

   // index.ts
   someV
   
   // repro.mjs
   import path from 'node:path'
   import { API } from 'typescript/unstable/sync'
   
   const api = new API()
   const root = process.cwd()
   const file = path.join(root, 'index.ts')
   const tsconfigPath = path.join(root, 'tsconfig.json')
   const snapshot = api.updateSnapshot({ openProject: tsconfigPath })
   const project = snapshot.getProject(tsconfigPath)
   
   console.log(project.checker.getCompletionsAtPosition(file, 5))

3. Run repro

   node repro.mjs
