Bug Report

Steps

This is an error related to using the latest version 0.80.0 that is not present in 0.79.0. During the build process with a typical webpack build you get the error: TypeError: instance.render is not a function

Expected Result

A build as it was in 0.79.0, which is completely stable with the exact same build process.

Actual Result

The actual result that happened 💣

Version

0.80.0 Webpack 4 Build is essentially the same as create-react-app, but with webpack 4 and decorators. Babel is using babel core 7.0.0-beta.48
