The blog page should show scheduled posts in the main loop. I've done that with this code:

/**
 * Show scheduled posts in main loop
 */
function fa_show_scheduled_posts( $query ) {

    if( $query->is_main_query() && ! is_admin() && $query->is_home() ) {
        $query->set( 'post_status', [ 'publish', 'future' ] );
    }
}
add_action( 'pre_get_posts', 'fa_show_scheduled_posts' );

But there's a different section that shows the 4 latest posts with a WP_Query. Even if I change the post status to only be published posts, it shows the scheduled posts.

Is there a way to show them in the main loop but not the WP_Query?

My WP_Query code:

      <?php
      $args = array(
      'showposts' => 4,
      'post_status' => array( 'publish' )
      );

      $the_query = new WP_Query( $args );
