cy.stub matchMedia to set dark mode causes other (not stubbed) calls to fail

[monktana]

Hello, i have come across this issue on my google search to solve an issue i currently have with stubbing the matchMedia function.

I'm have a test case to ensure that my color mode toggle works the way i expect it to. Therefore, i want to (pre)set the dark mode in the test following this blogpost: https://www.cypress.io/blog/2019/12/13/test-your-web-app-in-dark-mode

cy.visit('/', {
  onBeforeLoad(win: Cypress.AUTWindow) {
    cy.stub(win, 'matchMedia')
      .withArgs('(prefers-color-scheme: dark)')
      .as('set dark mode')
      .returns({
        matches: true,
        addListener: () => {},
      });
  },
});

When executing the test, i get this error message:

Can someone tell me why this fails? Do i need to manually create another stub for no arguments (or the 'prefers-reduced-motion')?

What is the return of the automatically created stub?

Thanks in advance :)
