NativeScript Angular + Karma - ReferenceError: window is not defined

So I decided to add unit testing to my NS7/NG11 app, followed instructions from NS website and got to the point where the app would start but the screen is blank (all white).

Initialized tests with ns test init, manually updated karma-webpack in package.json to v 5.0.0-alpha.5 as the default one had a bug that was fixed and should be released soon.

Command used to start testing is: ns test run --emulator

Testing in Tabs template with Angular. When running ns run ios --emulator the runs just fine and is usable.

Below is my package.json:
