[Bug]: getByRole does not accept RegExp v flag in the name option

[TaishiKobari]

Version

1.61.0

Steps to reproduce

Repro repo: https://github.com/TaishiKobari/playwright-issue-regex-v-flag

1. Clone the repro repo
2. Run pnpm install
3. Run pnpm test

The repro contains two tests against https://playwright.dev/:

• page.getByRole("link", { name: /Get started/v })
• page.getByRole("link", { name: /Get started/ })

The second test passes, but the first one fails.

Expected behavior

Both tests should pass.

Actual behavior

Only the test without the v flag passes.
