Cypress failed to run with infinite loading after last async event in Onfido IFrame

[danil-florko]

I faced with an issue for Onfido flow test.

Steps (environment) for testing:

1. Opened main page
2. The content of the page is inside Iframe ("parent Iframe" bellow);
3. Clicked button inside parent Iframe, Onfido Iframe has been opened (so Onfido Iframe is opened inside another Iframe);
4. All steps of Onfido verification are successful until confirmation, including video check;
5. Once confirmation button is pressed, request to Onfido API is sent;
6. Right after request, all test scenarios are disappearing from the left bar and infinite loading is appearing

Expected result is:
Cypress should wait until request will be sent to Onfido api and then continue with next scenarios from the test

Not sure but I suppose that the reason is because of nested Iframes and Cypress is not able to handle async events inside of them.

Could you help to solve this issue?
