Angular 19 specs won't run

When using this library in an Angular 19 application, I'm having an issue running my test suite. None of the tests run due to the following:

✔ Browser application bundle generation complete.

./node_modules/plotly.js-dist-min/plotly.min.js - Error: Module not found: Error: Can't resolve 'elementary-circuits-directed-graph' in '.../node_modules/plotly.js-dist-min'

I'm not sure how to diagnose this and the plotly.js github doesn't show any issues like this in their repository. Could I get some help getting pointed in the right direction on diagnosing the issue here and overcoming it?

For what it is worth, the plots work great when serving the application, so I'm hopeful that there is something I need to do to get my specs running again.

Commencez par reproduire l’échec de la suite de tests Angular 19 et examinez les erreurs de résolution de modules signalées pour node_modules/plotly.js-dist-min/plotly.min.js. Comparez le build de test avec le build de serving, puis confirmez que les dépendances manquantes sont résolues et que les specs s’exécutent correctement.
