Will be fixed today. Thank you for a report.

Meanwhile you can downgrade to the beta-13. It does not contain a bug.

Thanks!

For anyone following, I _believe_ you have to manually add/pin "react-stand-in": "4.0.0-beta.13" in your package.json, otherwise even [email protected] will still get beta.14 of react-stand-in, which is where this issue comes from.

Oh :(

Released in beta-15.
