Version

master after merging #3022.

Describe the bug

The bundle contains ES5 code because #3022 introduced a package that is not compatible with IE11 and ES5 browsers.

Steps to reproduce

1. On IE11, browse to https://corinagum.github.io/WebChat-release-testing/02.babel-standalone/index.html

Expected behavior

The page should load under IE11.

Instead, an error was thrown in the console, about syntax error.

Additional context

This is related to #3022.
