window.location.replace not working - inserts `__` into url

Current behavior:

Navigating within our application using location.replace("") in a chained promise handler throws a cross-origin error. In our actual application, we are waiting on a network request, then navigating using location.replace() in a then handler.

I’ve simplified the code to the most basic thing I can, and am able to reproduce by calling location.replace() in a simple setTimeout.

window.location.replace("") – works

setTimeout(() =>{
  window.location.replace("");
});

– gives the following error: SecurityError: Blocked a frame with origin "http://localhost:58236" from accessing a cross-origin frame.

Desired behavior:

I need to be able to call location.replace() in a chained promise handler.

Steps to reproduce: (app code and test code)

This fix is available starting in 4.6.0 as an experiment which you can access by setting this config option in your cypress.json or elsewhere:

{
	"experimentalSourceRewriting": true
}

The fix is experimental, so there may be some situations where the _/ rerouting is not fixed.

If you’re still experiencing _/ rerouting while setting the experimentalSourceRewriting to true in 4.6.0 - open a new issue with a reproducible example + screenshots, etc - filling out our issue template.
