Gutenberg SDK: Importing "loadScript" Library Into Block Fails

[jeffersonrabb]

Steps to reproduce

1. Add the following import to the editor.js file of any block found in client/gutenberg/extensions: import { loadScript } from 'lib/load-script';
2. Build the block using the SDK, e.g.: npm run sdk gutenberg client/gutenberg/extensions/presets/jetpack -- --output-dir=PATH_TO_JETPACK_REPO/_inc/blocks
3. The SDK should build successfully with no errors.
4. Add the block to a post in a browser. You should see the following error in the Javascript console:

What I expected

Library would be successfully imported and useable within the block.

No longer relevant, as we've been using Webpack Dynamic Imports instead.
