How to get rid of extra Untitled Article in html5 document outline when using new WP_Query?

Putting the answer I received via Twitter here for others to see:

It was the sticky post under the Featured Comic section that was creating that phantom Untitled Article. So, by adding:

'post__in' => get_option( 'sticky_posts' )

to the arguments, it got rid of it. New code for the Featured Comic now looks like this:

<?php 
$featured_comic_args = array(
    'posts_per_page' => 1,
    'post__in'  => get_option( 'sticky_posts' ),
    'ignore_sticky_posts' => 1,
    'tag' => 'buy-me, buyme',
); 

$featured_comic = new WP_Query( $featured_comic_args ); ?>
    <?php if ( $featured_comic->have_posts() ) : ?>
    <?php while ( $featured_comic->have_posts() ) : $featured_comic->the_post(); ?>
                <?php get_template_part( 'content-homefeatured' ); ?>

    <?php endwhile; ?>
    <?php wp_reset_postdata(); ?>
    <?php else: ?>
    <?php endif; ?>

Hope that helps someone else!
