Minor bug in Refined GitHub, but we need your help to fix it:
https://github.com/sindresorhus/refined-github/issues/565

We'll need to know:

1. Are you running two extensions at once? Chrome Web Store + development. If so, just disable one of them.
2. Are you on GitHub Enteprise?
3. The content of the console of this page.
4. The content of the console of the background page after enabling the Developer mode in the Extensions page: https://i.imgur.com/zjIngb4.png

Thank you! 🎉
❤️💛💚💙💜❤️💛💚💙💜❤️💛💚💙💜❤️💛💚💙💜`);
