wp-includes/comment-template:comment_form() calling comment_open() without passing $post_id

[insertvisionhere]

Although you can pass a post_id to wp-includes/comment-template:comment_form()in order to specify which post to add a comment form to, on line 1553 this function calls if( comments_open() ) but doesn't pass it through the post_id argument.

I encountered this bug by using ajax to call a page with a custom post type from a standard page. The page called via ajax calls comments_template() which in turn calls comment_form() and passes it the post_id of the ajax page, however that post_id doesn't make it to comments_open() meaning it searches for comment status on the standard page and not the page called through ajax.

This can be fixed by changing <?php if ( comments_open() ) : ?> on line 1553 to <?php if ( comments_open($post_id) ) : ?>
