Intercept does not work between tests (`it`)

Current behavior

We intercept every request call that goes out of cypress to add an AUTH header to every request. When the header is not attached we get network requests that fail. Before when using Cypress 6.8, all requests were intercepted even between tests (it). Now that is not the case anymore. This causes our tests to flake very frequently.

Desired behavior

Intercept all requests!

Test code to reproduce

You can reproduce the errors pretty consistently with the repo: https://github.com/giacaglia/cypress-test-tiny

You need to run both the frontend and the backend to test it out.

I can confirm that I’m still seeing this behavior in cypress v10.6.

My use case is defining intercepts in a beforeEach hook. It appears that a test can complete, yet the page can still trigger a network request while the next test’s beforeEach hook is running (which is prior to those network request intercepts being defined).

In other words:

1. Test1 a. beforeEach: define some intercepts b. run the test c. test passes
2. Test2 a. beforeEach: define some intercepts… FAILURE! Network requests triggered from Test1 are showing up in the beforeEach step, prior to intercepts getting defined!

Would love any updates on this issue!
