Custom components not working with native federation

[maiksfd]

Describe the Bug

I successfully integrated the form editor with the custom range component in my angular application. The goal is to use this application as a microfrontend. The problem is, as soon as i add native federation (https://www.npmjs.com/package/@angular-architects/native-federation), the custom component (and the whole editor) is not working anymore.

Steps to Reproduce

1. Clone the repo: https://github.com/maiksfd/angular-form-js-test
2. Start both apps
3. Drag the custom range component into the editor

Expected Behavior

The custom component should also render in the application with native federation.

Actual Behavior

When dragging the custom component into the edior, the following error is displayed:
ERROR TypeError: r2 is undefined

After the error the whole editor stops working (not able to drag any components into the editor).

Screenshots

Additional Information

bpmn-io/form-js: 1.10.1

As far as i know, native federation uses esbuild under the hood, so it should not make any difference (esbuild is used in the application without native federation too and it works there).

Any help is appreciated :)
