Possible IE issue with an Event object

[jvorcak]

I'm trying to create a higher abstraction on top of this awesome plugin. Something not that low level - OOTB solution with support for emojis & markdown.

However, in IE I experience this issue.

Steps to reproduce:

1. Clone https://github.com/webscopeio/react-markdown-editor
2. yarn && yarn start
3. In a second terminal, cd example && yarn && yarn start
4. Open page in IE11

I've included babel-polyfill in my example project.

We are using Babel preset from CRA https://github.com/facebook/create-react-app/tree/next/packages/babel-preset-react-app

Object.entries is not polyfilled by default and it should be polyfilled manually.

But babel-polyfill should be enough to do so. How did you include it?

EDIT: Closing for now, but let's continue the discussion if need any.
