With Cypress, you can easily create tests for your modern web applications, debug them visually, and automatically run them in your continuous integration builds.

Hey,
I am starting to introduce Cypress to our company and am writing the first e2e tests right now. 
We are using a CookieBanner from CodeCentric which I would like to disable programatically.

Working with `cypress open` and having an actual browser where the test runs the following code is working:

```ts
beforeEach(() => {
    Cypress.on("window:before:load", (window) => {
    window.localStorage.setItem("some_key", "some_value")
    window.localStorage.setItem("another_key", "another_value");
  })
})
```

But running this with `cypress run --headless --browser electron` does not work and it seems like that the items are not set inside `localStorage`. I tried to check it with 

```ts
expect(localStorage.getItem("some_key")).to.not.be.null;
expect(localStorage.getItem("another_key")).to.not.be.null;
```

Is there a way to set some `localStorage` items in the headless mode to get rid of my cookie banner?
