Loop through wordpress' the_post_navigation() function

问题

Is it possible to loop through the the_post_navigation() function?

Now, when I am at the end of the post loop, the 'next post' button simply disappears. I want this button to stay, and to navigate to the first post. This way, the navigation keeps looping through the posts.

This is the code btw:

<div class="case-nav hidden-xs">
 <?php the_post_navigation( array(
  'prev_text' => __( 'Previous post'),
  'next_text' => __( 'Next post'),
 )); ?>
</div>

EDIT

This is a shorter version for infinite looping between posts.

/* Infinite next and previous post looping */
if( get_adjacent_post(false, '', true) ) { 
    previous_post_link('%link', '&larr; Previous Post');
} else { 
    $first = new WP_Query('posts_per_page=1&order=DESC'); 
    $first->the_post();
    echo '<a href="' . get_permalink() . '">&larr; Previous Post</a>';
    wp_reset_query();
}; 

if( get_adjacent_post(false, '', false) ) { 
    next_post_link('%link', 'Next Post &rarr;');
} else { 
    $last = new WP_Query('posts_per_page=1&order=ASC'); 
    $last->the_post();
    echo '<a href="' . get_permalink() . '">Next Post &rarr;</a>';
    wp_reset_query();
};

Okay, I solved it myself, in a different way. But the result is the same!

<!-- Navigation -->
                    <div class="case-nav hidden-xs">
                        <?php the_post_navigation( array(
                        'prev_text' => __( 'Vorig bericht'),
                        'next_text' => __( 'Volgend bericht'),
                        )); ?>
                    </div>
                    <div class="case-nav visible-xs">
                        <?php the_post_navigation( array(
                        'prev_text' => __( 'Vorige'),
                        'next_text' => __( 'Volgende'),
                        )); ?>
                    </div>
                    <?php

                    // Get first post
                    $args = array(
                    'offset'           => 0,
                    'category'         => '',
                    'category_name'    => '',
                    'orderby'          => 'ASC',

                    'include'          => '',

                    'post_type'        => 'post',
                    'post_mime_type'   => '',
                    'post_parent'      => '',
                    'post_status'      => 'publish',
                    'suppress_filters' => true
                    );
                    $posts_array = get_posts( $args );
                    $firstPost = get_permalink($posts_array[0]->ID);

                    //Get latest post

                    if(have_posts());
                    while(have_posts()) :
                    the_post();
                        $lastPost = get_permalink();
                    endwhile;
                    wp_reset_query();
                    ?>

                    <script type="text/javascript">
                    var itemNext = "<?php echo $firstPost; ?>";
                    var itemPrev = "<?php echo $lastPost; ?>";
                    //      remove nav line if nav item doesn't exist
                                if(!$('.nav-previous').length){

                                } else if(!$('.nav-next').length){
