Line numbers are shown incorrectly when ussing mock-fs package.

• Issue

If you use mock-fs package the line numbers are shown icorrectly.

import Dog from "./Dog";
import * as mock from "mock-fs";

describe("Dog", () => {
	
	beforeAll(() => {
		mock({
			"path/to/file.txt": "my text content",
		});
	});

	afterAll(() => {
		mock.restore(); 
	})

	
	test("should woof", () => {
		const dog = new Dog();
		expect(dog.woof()).toBe("Woof!____ SHOULD FAIL AND DISPLAY LINE NUMBER 19");
               // but it shows error at line number 16
	});
});

• Expected behavior

When running the tests, the line number should be shown correctly. But instead the JS line number is shown (not the TS input file line number)

• Link to a minimal repo that reproduces this issue

• Optional (but highly recommended) - Configure Travis (or your favorite system) with the minimal repo

I cannot configure it because the test NEEDs to fail to show the line number.

@jhm-ciberman allowSyntheticDefaultImports needed to be set to true when using default imports. I’ve sent a PR with the patch to the linked repo. Let me know if that works for you

@thiagoh is it the same issue your facing?

In either case, it would be better to open a new issue (link to this if it helps) so that your specific case can be discussed/fixed there
