Description of the issue

Our repo uses GitHub Actions and JavaScript / TypeScript CodeQL default configuration.

In addition, these events will trigger by push and pull request.

However, the Code scanning doesn't run in this part1 pull request.

The part2 and part3 aren't scanned, either.

On the other hand, the part4 pull request got the CodeQL scan result.

Moreover, the code scanning works correctly on every push events.

Why doesn't the code scanning run on every pull request?
