An in-range update of core-js is breaking the build 🚨

[greenkeeper[bot]]

Version 2.5.0 of core-js just got published.

Branch	Build failing 🚨
Dependency	core-js
Current Version	2.4.1
Type	devDependency

This version is covered by your current version range and after updating it in your project the build failed.

As core-js is “only” a devDependency of this project it might not break production or downstream projects, but “only” your build or test tools – preventing new deploys or publishes.

I recommend you give this issue a high priority. I’m sure you can resolve this :muscle:
