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 'd3-array' in '.../node_modules/plotly.js-dist-min'

./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.

Reproduzieren Sie zunächst den Fehler der Angular 19-Testsuite und untersuchen Sie die für node_modules/plotly.js-dist-min/plotly.min.js gemeldeten Fehler bei der Modulauflösung. Vergleichen Sie den Test-Build mit dem Serving-Build und bestätigen Sie anschließend, dass die fehlenden Abhängigkeiten aufgelöst sind und die Specs erfolgreich ausgeführt werden.
