 Since 6.2, any "classic" theme that hooks the core "Post Featured Image"
 block before the loop causes the content within the loop to disappear.

 To replicate:

 1. Use a "classic" theme like Twenty Twenty Two.
 2. Hook the Post Featured Image block into the theme before the loop
 begins:

 {{{#!php
 <?php
 add_action( 'wp_body_open', function() {
         $block_content = '<!-- wp:post-featured-image /-->';
         $block = parse_blocks($block_content)[0];
         echo render_block($block);
 } );
 }}}

 3. View a single post.

 The content will be gone.

 This is an issue if any theme is allowing users to insert this block as a
 page hero before the loop begins.
