Keep existing classes when importing templates?

Before version 1.12:
When importing templates, if an element had a class that already existed in your site, Bricks would keep that class and use your existing class styles.

After version 1.12:
Bricks now removes any duplicate classes during template import. The imported elements arrive without those class names attached.

The Global Class Import Manager doesn’t seem to provide an option to restore the old behavior of keeping duplicate classes.

I have the same issue with importing frames and acss utility classes, I think it was your post on their forum I saw?

I dont know if it may help but I developed this feature on my child theme maybe it solves it try it

I dont have any css lib I usualy dont need so cant test it
