Cookies are not set if authentication service is on a different port than web app

[lgodziejewski]

Current behavior:

Our application has separate services responsible for authentication and delivering our web app. On local environment that would be localhost:4100 and localhost:3000.

baseUrl is set to localhost:3000

Running this code in tests fails:

cy.visit('/');
cy.request({
  method: 'POST',
  url: 'http://localhost:4100/session',
  headers: {
    'content-type': 'application/vnd.api+json', // required by our backend
  },
  body: {
    // credentials as needed
  },
});

cy.getCookie(<session cookie name>).should('exist'); // this fails :(

It would seem that cypress.request() on purpose isolates cookies between different ports of the same domain?

Desired behavior:

As this works in Chrome or any tested (Firefox, Safari, Edge - to be explicit :-) ) other browser, I think
cookies should be set, as described e.g. in this answer

If a global change would be an issue, maybe localhost could be an exemption?

Steps to reproduce:

• have separate services with authentication and web-app available on different ports
• set the web-app as baseUrl
• make a request to the auth api (as in the code above), response contains set-cookie
• cy.getCookies() returns empty array
