Cypress clears cookies before JavaScript is terminated

See original GitHub issue

Current behavior

When Cypress starts executing a new test, it will clear all cookies even if the JavaScript code in the old test is still executing. This can be the source of confusing errors reporting 401 responses from the backend where Cypress wrongly reports them as having been triggered by beforeEach.

Desired behavior

Make sure that the JavaScript code from the previous test has stopped or block all network traffic between tests before clearing all cookies.

Here’s a minimal example to reproduce the issue. It’s still present in 7.4.0

<!DOCTYPE html>
<script>
  document.cookie = "foo=bar"
  let interval = setInterval(() => {
    if (document.cookie !== "foo=bar") {
      clearInterval(interval)
      throw new Error(`Invalid cookie ${document.cookie}. Hash: ${document.location.hash}`)
    }
  }, 10)
</script>

it("first", () => {
  cy.visit("./index.html#first")
  cy.wait(1000)
})

it("second", () => {
  cy.visit("./index.html#second")
  cy.wait(1000)
})

The first test case always passes. The second always errors because the first instance of the app (as witnessed by the #first location) crashes.
