@cypress/react and react-helmet. Can they work together?

[glomotion]

So the cypress docs mention things like cy.title() to verify that the document.title is updating as things in react trigger title changes via react-helmet...

Sadly though, when @cypress/react components are being tested (eg inside cypress run-ct) cy.title() ALWAYS returns the same string: Components App.

Has anyone managed to get @cypress/react & react-helmet working together (so that helmet actually updates cy.title, for example)?

FWIW, we tried to catch helmet updates from within the fixture, but no joy (see screenshots).

I think because the helmet is really meant to operate at the top level - at the document level, a more appropriate test here would be an E2E test, not a component test.
