-// 👋 Hola! I'm here to help you write a great bug report pull request.
-//
-// You don't need to fix the bug, this is just to report one.
-//
-// The pull request you are submitting is supposed to fail when created, to let
-// the team see the erroneous behavior, and understand what's going wrong.
-//
-// If you happen to have a fix as well, it will have to be applied in a subsequent
-// commit to this pull request, and your now-succeeding test will have to be moved
-// to the appropriate file.
-//
-// First, make sure to install dependencies and build React Router. From the root of
-// the project, run this:
-//
-//    ```
-//    pnpm install && pnpm build
-//    ```
-//
-// If you have never installed playwright on your system before, you may also need
-// to install a browser engine:
-//
-//    ```
-//    pnpm exec playwright install chromium
-//    ```
-//
-// Now try running this test:
-//
-//    ```
-//    pnpm test:integration bug-report --project chromium
-//    ```
-//
-// You can add `--watch` to the end to have it re-run on file changes:
-//
-//    ```
-//    pnpm test:integration bug-report --project chromium --watch
-//    ```
