Comment (by salvoaranzulla):

 Hi,

 Here is an update with latest WordPress version (6.2). I confirm that the
 bug is also in the last version of WordPress.

 1) On wp-includes/media.php I have added:

 {{{#!php
 <?php

 print_r($content_media_count); // added to see the counter
 }}}


 after

 {{{#!php
 <?php
 // Increase the counter since this is a main query content element.
 $content_media_count = wp_increase_content_media_count();
 }}}


 On my archive page, I see:

 2) My archive code page is the following:


 {{{
                 <?php
                         $p = 0;
                         $i = 0;
                                 while ( have_posts() ) : the_post();
                                 if($p == 0):
                         ?>
                 <article class="contentPreview">
                         <header>
                                 <a href="<?php the_permalink(); ?>"><span
 class="heading2"><?php the_title(); ?></span></a>
                         </header>
                         <p class="column"><?php the_excerpt(); ?></p>
                         <figure class="column">

 array( 'alt' => get_the_title())) ?>
                         </figure>
                 </article>
                 <div class="articleGrid">
                         <?php
                                 else:
                                 if ($i % 2 == 0) echo '<div class="row">';
                         ?>
                                 <article class="contentPreview column">
                                         <header>
                                                 <a href="<?php
 the_permalink(); ?>"><span class="heading4"><?php the_title();
 ?></span></a>
                                         </header>
                                         <p class="small"><?php
 the_excerpt(); ?></p>
                                 </article>
                         <?php
                                 if ($i % 2 != 0) echo '</div>';
                                 $i++;
                         ?>
                 <?php endif;  $p++;  endwhile; ?>
                 </div>
 }}}


 3) The "loading=lazy" has been added to the images because WordPress
 thinks that the image is the image number 10 (my post has 9 images
 inside).
