How do I confirm a javascript prompt in Cypress?

[DiogoManzoli]

After I click on a button, this confirm window appears, but I didn't find anything that confirms this prompt

Part of the code that opens the prompt:

 cy.get("iframe")
      .its("0.contentDocument")
      .its("body")
      .find("#f_bln_assistencia_confirmar")
      .click();

Help me??

I believe this may be related to the Chrome team deprecating the unload event. It seems that Cypress no longer has the ability to automatically accept/dismiss window:alert objects. This bug is causing major issues for my team, and we would love a resolution. cc @jennifer-shehane

A workaround may be to stub the event:
cy.on("window:confirm", cy.stub().returns(true))

If Cypress is no longer auto closing then yea I guess that's a bug, which as you mentioned @samelawrence might be due to browser APIs changing. Does the confirm go away in Firefox?

@samtsai This issue has been reproduced by Cypress staff in all browsers and is tracked in this issue.
