Show how to stub window.print

[bahmutov]

• from regular button calling window.print in its window
• when the app is using something like https://github.com/gregnb/react-to-print which creates a temporary iframe with its own window

@bahmutov any luck with react-to-print? I've stumbled upon your snippet here but it does not seem to work - the test just hangs

No, I did not have time to do this unfortunately
