“Add modal” blueprints not picked from theme’s blueprints folder

Would anyone know how to make admin “see” blueprints specified via add_modal configuration option within theme’s blueprints folder?

If I place ‘admin/pages/new_post.yaml’ under ‘user/blueprints’ it works. If I place it under ‘theme/active_theme/blueprints’ it does not work.

I’ve gone as far as doing scanBlueprints() within an appropriate event handler in the theme - nothing.

Start by tracing the add_modal configuration and the blueprint discovery path around themes/grav/templates/pages.html.twig#L360. Compare the working user/blueprints path with theme/active_theme/blueprints, and inspect the scanBlueprints() call mentioned in the issue. Done means an admin modal blueprint in the theme’s blueprints folder is discovered and usable.
