Cannot click 're-run all checks' on Actions page #2328

If you're on the latest beta of GitHub Actions, there's a drop-down for re-running all checks that you can't click.

I can confirm that it works fine on Firefox and in Chrome after I've disabled the extension.

Example URL — https://github.com/paambaati/websight/pull/10/checks?check_run_id=193115347
