Duplicate declaration "bpfrpt_prototype_Scroll"

See original GitHub issue

Reporting a Bug?

The built es version of https://unpkg.com/react-virtualized@9.18.4/dist/es/List/List.js has a duplicate declaration of a named import. You can see it at the bottom of the file:

import { bpfrpt_proptype_Scroll } from '../Grid';
// ...
import { bpfrpt_proptype_Scroll } from './types';

Found this gives me an error in storybook/webpack:

I’m not sure how this happened. I looked at the source code and I don’t know where those declarations are coming from… 🤔

@bvaughn Reverted changes to 9.18.0. Deprecated broken releases. Published 0.18.5. I guess we need to build examples from built files to catch such gotchas.

Sorry for broken releases, guys.

I’ve also encountered this issue when bundling code with webpack.

Also, when bundling code with browserify I get Uncaught ReferenceError: bpfrpt_proptype_ScrollIndices is not defined

Both this issues did not occur in version 9.18.2
