importing the sdk causes a warning in webpack

[jooohn]

Maybe because of this parcel's issue (parcel-bundler/parcel#2883), I've run into the same problem (https://github.com/jooohn/reproduce-contentful-ui-extensions-error).

I believe it's not originally this sdk's problem, but I want to know when the problem is fixed anyway!

@jooohn Thanks for creating a repo with a reproduced issue!

What problems does this warning cause? From what I see at webpack/webpack#196, it a long-running issue with Webpack and I'm not sure if we should act on it.

According to this issue, a library built with percel causes the warning when the built js is bundled with webpack by library users.

I think it's an issue of either webpack or parcel, so possible approaches would be like this:

1. Wait for webpack fixes the issue.
2. Wait for parcel to fix the issue, and then build this SDK with the new version of parcel.
3. Build this SDK without parcel.

Hi,
I'm encountering the same issue when importing this into a create-react-app project. Are you aware of any way to fix it?

I get the same thing using webpack and vue.

App.vue

import { init as initContentfulExtension } from 'contentful-ui-extensions-sdk'

export default {
  data () {
    return {
      extension: null
    }
  },
  created () {
    initContentfulExtension((extension) => {
      this.extension = extension
      this.extension.window.startAutoResizer()
    })
  }
}

This causes build failures on Netlify with apps created using the create-contentful-app utility, because it uses create-react-app (webpack) that treats warnings as errors during CI builds; contentful/create-contentful-app#15

I believe this issue should be fixed in newer versions of the SDK, as we're no longer using parcel in this repo. Please feel free to open a new issue if this is still causing you problems.
