Woocommerce: custom loop in product tabs breaks reviews tab

I found the solution which is probably quite basic for experienced WP developers. I’m gonna post it here instead of deleting the question though, I hope this might help someone someday…

The issue was that the post data wasn’t reset, so all I needed is to add a function call wp_reset_postdata(); after my while loop. Like so:

$crosssell_ids = get_post_meta( get_the_ID(), '_crosssell_ids' ); 
$crosssell_ids = $crosssell_ids[0];

if(count($crosssell_ids) > 0) {
    $crosssell_args = array( 'post_type' => 'product', 'posts_per_page' => 8, 'post__in' => $crosssell_ids );
    $crosssell_loop = new WP_Query( $crosssell_args );
    echo '<div class="products"><div class="tabs-title">Consumables for <br>&laquo;' . get_the_title($product->id) . '&raquo;</div>';
    while ( $crosssell_loop->have_posts() ) {
        $crosssell_loop->the_post();
        wc_get_template_part( 'content', 'product' );
    };
    wp_reset_postdata();
    echo '</div>';
}
