 Filter wp_content_img_tag seem (in a block theme) seem to run 3 times on
 content images and 2 times on custom logo image. Simple code to expose the
 problem:

 add_filter( $hook_name='wp_content_img_tag', function( $filtered_image,
 $context, $attachment_id ){ return 'a:'.$filtered_image; },$priority=21,
 $accepted_args=3 );
