Telling Jest to not mock /moment(-timezone)?/ not working - unit-testing

Question

Getting an error with jest where anytime moment/moment.tz() is called, TypeError: (0 , _moment2.default)(...).tz is not a function is thrown. Below is my jest config with absolute paths redacted.

I've tried telling jest to jest.dontMock() as well as jest.unmock() but to no avail.
I've also tried require.requireActual().
I want to only mock moment when I specify per test (per file) with jest.mock().
What could be causing these issues? I am not mocking or unmocking moment anywhere in my test files. I've just simply used #vue/test-utils to mock entire computed properties using moment to get around this issue in the meantime.

You could try importing them directly in the tests. Also, I checked issues and other questions and it seems that importing timezone doesn't actually add the tz function to moment, so a way to solve it could be:
import moment from "moment-timezone"
