The X-theme registers the scripts in the admin_enqueue_scripts hook, and then attempts to enqueue them in the customize_controls_enqueue_scripts hook. However, the Enewsletter builder doesn’t call admin_enqueue_scripts until after customize_controls_enqueue_scripts has been called.

However this is a problem if other plugins attempted to enque scripts using the customize_controls_enqueue_scripts action that
depend on scripts that were registered in admin_enqueue_scripts
Would it be possible to modify Email_Newsletter_Builder to call admin_enqueue_scripts when the customize_controls_enqueue_scripts action is called.
