Interesting, because the PR has 10+ commits, it skips the PR labeler:

```
automate-prs-labels:
    # Greet first so that only the author gets that notification.
    needs: greeter
    runs-on: ubuntu-24.04
    # Ignore PRs with more than 10 commits.  Pull requests with a lot of
    # commits tend to be accidents usually when someone made a mistake while trying
    # to rebase.  We want to ignore these pull requests to avoid excessive
    # notifications.
    # always() means that even if greeter is skipped, this job will run.

      github.event.pull_request.draft == false &&
      github.event.pull_request.commits < 10
    steps:
      - uses: actions/labeler at 634933edcd8ababfe52f92936142cc22ac488b1b # v6.0.1
        with:
          configuration-path: .github/new-prs-labeler.yml
          repo-token: ${{ secrets.ISSUE_SUBSCRIBER_TOKEN }}
```

I guess they have some arbitrary limit for limiting the blast radius of people targeting the wrong base branch and tagging practically everybody.
