Cypress does not work in airplane mode or without network

[digitaldrummerj]

Current behavior:

When trying to run Cypress test without network or in airplane mode, the test window just shows a blank solid white screen and never brings up the tests. The website works just fine locally without network when I run everything locally.

Desired behavior:

Successfully launch and run the tests even without network or in airplane mode.

Steps to reproduce: (app code and test code)

1. Clone https://github.com/digitaldrummerj/angular-tutorial-code
2. cd into angular-tutorial-code
3. Checkout branch chapter-ui-tests (git checkout chapter-ui-tests)
4. run npm install
5. install Angular CLI (npm install -g @angular/cli)
6. run ng serve
7. run npx cypress open
8. click the "run all specs" button
9. all test should pass
10. close Cypress Chrome window
11. disconnect network or turn on airplane mode
12. click the "run all specs" button
13. the Cypress Chrome window should now just be a blank white window

@digitaldrummerj can you check v3.4.1 - I think this has been fixed, and your issue is duplicate of #4763
