Card component elements' display order is reverse in layout builder content preview

Problem/Motivation

Add an element using card component via Layout builder and display the preview of the content.
The header card elements is displayed after the card content :

When you are viewing the component not in layout builder preview, the card displays correcly :

Steps to reproduce

Proposed resolution

The code responsible of this behaviour seems to be a css library override in overrides.css of ui_suite dsfr theme :

.layout-builder__section .fr-card * {
  order: unset;
}

Why was this CSS originally written?
Is it possible to remove it?

Remaining tasks

User interface changes

API changes

Data model changes
