Importing in SCSS manifest breaks Codemirror

[spiderpug]

As the app I'm working on is using an application.scss instead of the application.css I tried to integrate this gem's stylesheets this way:

@import 'scrivito_codemirror_editor';

There is no error while importing it but the editor is not usable afterwards. It just shows a long list of blank lines and some weird, random strings at the end of it, possible the number of lines or similar:

Is there a plan to support SCSS integration as well?
