[Bug]: `--selectProjects` ignores file path arguments on Windows

[kbigdelysh]

Version

29.7.0

Steps to reproduce

1. Clone the reproduction repository at https://github.com/kbigdelysh/jest-windows-path-bug-reproduction
2. Install dependencies: pnpm install (or npm install)
3. Run the command: pnpm run test:specific (or npx jest --selectProjects unit src/__tests__/example-one.test.ts)
4. Expected: Should run 1 test suite (3 tests) from example-one.test.ts
5. Actual: Runs all 3 test suites (9 tests) - the file path argument is completely ignored

Additional verification:

• Running pnpm run test:workaround (uses --testPathPattern=example-one) correctly runs only 1 test suite
• This confirms --selectProjects specifically ignores file path arguments on Windows

Environment: Windows 10/11, Jest 29.7.0, Node.js v22.11.0, PowerShell

Expected behavior

Expected: Should run 1 test suite (3 tests) from example-one.test.ts

Actual behavior

Actual: Runs all 3 test suites (9 tests) - the file path argument is completely ignored

@kbigdelysh I don't see any test files in the repo for reproduction. Can you help filling in?
