Description

This is the code for render_block_core_comment_template() in block_library/comment_template/index.php:

	// Get an array of comments for the current post.
	$comments = $comment_query->get_comments();
	if ( count( $comments ) === 0 ) {
		return '';
	}

	$comment_order = get_option( 'comment_order' );

	if ( 'desc' === $comment_order ) {
		$comments = array_reverse( $comments );
	}

	$wrapper_attributes = get_block_wrapper_attributes();

	return sprintf(
		'<ol %1$s>%2$s</ol>',
		$wrapper_attributes,
		block_core_comment_template_render_comments( $comments, $block )
	);

That doesn't allow a plugin author to provide a custom ordering. In my case I am adding comment voting and we want to reorder comments by their up/down votes. The following line should be inserted prior to the $wrapper_attributes assignment:

	$comments = apply_filters( 'comments_array', $comments, $block->context['postId'] );

Step-by-step reproduction instructions

1. In any blocks-based theme create a plugin with a comments ordering filter using add_filter( 'comments_array', function ( $comments, $post_id ) { return array_reverse( $comments ); }, 10, 2 );
2. Create a post and add two or more comments
3. Load the post. Expected result: is comments in reverse order; Actual result: comments in original order
