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.

先重現 Angular 19 測試套件的失敗，並檢查針對 node_modules/plotly.js-dist-min/plotly.min.js 回報的模組解析錯誤。比較測試建置與服務建置，然後確認缺少的相依套件已解決，且各項 spec 均成功執行。
