⌛ 🐛 Featured image not rendering as background overlay in the Atomic Flexbox element

### Description

I am building a cpt single entry template and want to pull the featured image as background overlay in an Atomic flexbox element.

This gets rendered properly in the editor but not on the frontend and only applies when loading featured images (post featured image). It does not have issues when selecting an image directly from the library (not dynamically).

### Steps to reproduce

1. Create a single post template
2. Load the featured image as a background overlay on an Atomic Flexbox element
3. Set the proper display conditions to the single post template
4. Create a new post and assign a featured image
5. Preview the new post

### Expected behavior

It is expected that the featured image gets pulled dynamically on the frontend.
