I'm having issues whenever I press run a test

Whenever I press run a test, it doesn’t do anything but say “running tests” in green text. Can someone please help me? I’m using Microsoft Edge (Without Chromium).

User Agent is: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 Edge/18.18362.

Link to the challenge:

Microsoft Edge is known to have several issues with the test suite code. Have you tried running the tests in Chrome?

Yes, I ran the tests on other browsers. It worked fine. Since Microsoft is making the switch to Chromium, it won’t really matter in the future.
