 Gutenberg's "Post Comments" block appears to pull its code from the
 WordPress' theme compat `comments.php` file here:

 https://github.com/WordPress/wordpress-
 develop/blob/a0b1f27de6c928fde51bbc7078b32ca9c9d6ed8d/src/wp-includes
 /theme-compat/comments.php#L30-L75

 This includes some code comments that may be useful for developers, but
 don't actually need to be send to the front end:

 I'd suggest we change these from HTML comments to PHP comments, so they
 aren't visible in the outputted markup.
