Foundation.addToJquery() & 6.7.4 issue

[markbyart]

Hi Foundationers

I've run in to an issue upgrading from 6.7.3 to 6.7.4 via npm. In 6.7.4, when I compile the JS & SASS (Webpack) and run my Drupal site locally, I get a TypeError, foundation is not a function, which I don't in 6.7.3—it works as expected.

My setup is as follows:

window.js:
// Drupal includes jQuery already
export const $ = window.jQuery;

app.js
import { $ } from './window';
import { Foundation } from 'foundation-sites';
Foundation.addToJquery($);

export default function app() {
    $(document).foundation();
    $('document').ready(() => {
        // Stuff
    })
}

Any ideas? Am I doing something wrong here?

Node 16.4.2
NPM 8.5.5
Webpack 5.70.0

Thanks!
