Chrome cy.visit breaks testpage, but works in Electron

Current behavior:

When running a cy.visit in Chrome 74 the testpages turns nearly blank and displays Cannot GET /__/. However it does visit the page when Electron is used.

1. Running test

2. Redirect?

Config

Desired behavior:

The cy.visit() call should show the served page at localhost:8080 in an iframe. The testpage should stay visible (as seen in screenshot 1).

Steps to reproduce:

The following test redirects to the page shown in the screenshot:

cy.visit('http://localhost:8080/index-mocks.html');

Versions:

Windows 10

$ ./cypress --version
Cypress package version: 3.3.0
Cypress binary version: 3.3.0

@RicardoVaranda You may be able to delete the policy yourself if you have local administrator access.

Sidebar: It’s especially unfortunate that so many companies have this policy set, as forcing a proxy is basically just security theater. It does nothing to make you more secure. Users can get around being forced to use a proxy by using other browsers that don’t respect policy, like SRWare Iron, or by injecting a DLL that blocks the policy. Of course, your company’s network will not allow Internet access without going through the proxy, which also makes forcing ProxyMode redundant. 🙄

We have also been facing this issue for quite some time now and had to use electron to bypass it. It would be great to get a fix.
