Steps to reproduce

• Clone the reproduction repository
• npm i
• npm run serve

What is expected?

The neon-btn.css in src/components/ExampleButton/ExampleButton.scss is imported and the styles are visible in the shadow-root.

What is actually happening?

The styles are not imported and the @import "~neon-button-css/neon-btn.css"; statement is directly rendered to the shadow-root styles.
