Hi @codeqlhelper,
Thanks for your contribution ❤️ I hope you don't mind that I pushed a few administrative commits to the PR:
- I updated the change note to be more aligned with the way we normally phrase FP removals
- I added a very minimal set of tests to this query since I couldn't find any tests for it (😱) and we like to have tests in place for changes like this.
- The query had to be autoformatted to match our style guide (see here)
Everything LGTM now!
