v12.7.15 Tests don't pass on Windows 10

[Smolations]

1. I can't create a PR because all I did was clone this repo on my machine and run npm test.
2. I recognize that this may indeed actually be an issue for karma-edge-launcher but you should be aware that your test suite is currently failing on windows.

As for what happens on my machine for the above, or more directly, npm run test:browser, I see chrome open up with a karma status, and Edge open with a tab, then another tab in 10seconds or so, then another tab in another 10 seconds or so, then the process dies. None of the Edge processes are ever successfully killed and subsequent tests do not appear to get run.

Again, given that this is ultimately likely to be not your problem, feel free to close. This is more-or-less just a notification (and I did post in the discord but received no response after 24hrs).

Thank you for investigating.
I removed the edge launcher now. It looks like it is outdated anyway and the last release is 5 years old.

[Smolations]

@pubkey Would it be possible to add an additional tag on the stable branch with this change so I can re-test? Or should I just apply your commit to a local branch if I'm working with v12?

[pubkey]

Add it to your local branch please. I am just a single developer, i cannot maintain old versions atm.
