 To reproduce this issue: 1. Create a meta box with an id that has
 underscores(id_with_underscores). 2. Try to put the box after the title.
 Nothing happens. Replace the underscores with dashes and everything works
 as expected.
 {{{#!php
 <?php
 // Render metabox
 function render_metabox(){
 ?>
 <h2>Test</h2>
 <?php
 }
 // Define meta box
 add_meta_box(
                         'test_underscore_metabox',
                         __( 'Person Details', 'text-domain' ),
                         'render_metabox',
                         'post',
                         'advanced',
                         'high',
                         null
                 );
 function move_metabox_after_title() {

         global $post, $wp_meta_boxes;

         do_meta_boxes( get_current_screen(), 'advanced', $post );

         unset( $wp_meta_boxes[ get_post_type( $post ) ]['advanced'] );
 }
 add_action( 'edit_form_after_title', 'move_metabox_after_title' );
 }}}
