Describe the Problem

Expected behavior:

Using CodePane with lang="json" fails in production build, although it works during npm start.

The error is:

TypeError: Cannot read property ‘rest’ of undefined at Object.tokenize (prism-core.js:251)

Closing for lack of response and because I think this was fixed in our most recent release, which updates the usage of react-live. Feel free to re-open this issue if the bug persists.
