Text format form element

Maybe in preprocess form element condition about mb-3 to replace by:

      $this->variables->addClass('mb-3');
      // If the element is a sub-element of a text_format do not add the class.
      if (key_exists('#format', $variables['element'])) {
        $this->variables->removeClass('mb-3');
      }

(I am currently testing gin_lb but this may also occur in standard Layout Builder offcanvas)

Not needed for the moment. In my subtheme for Gin LB support I removed Ui Suite Bootstrap processing.
