H1 whithin the product category description converted to uppercase

Hi
I had this thread open: https://kriesi.at/support/topic/show-product-category-description-even-when-there-is-no-products/#post-1358508
I have the solution of the above thread working, however, because the search results uses a page template, the H1 in the description editor gets converted to uppercase. All other product categories use the shop template and the H1 is in normal sentence case.

How to I maintain consistency by having the H1 display in sentence case on the search result page?

Here’s the code snippet I have and would it be appropriate to add CSS for the H1 within it?

function archive_description_callback() {
	$term_object = get_queried_object();
	$archive_description = $term_object->description;
	echo '<div class="archive-description">'.$archive_description.'</div>';
    return $output;
}
add_shortcode( 'archive_description_shortcode', 'archive_description_callback' );
function add_archive_description_shortcode() { ?>
    <script>
  (function($){	
      var short_code = '<?php echo do_shortcode("[archive_description_shortcode]"); ?>';
	  if ($('#top.archive.tax-product_cat .entry-content-wrapper').attr("id") == "search-fail") {
      $(short_code).insertBefore( ".woocommerce-products-header" );
	  }
  })(jQuery);
  </script>
    <?php
  }
  add_action('wp_footer', 'add_archive_description_shortcode');

Thank you
