 The gif above should be self-explanatory. It adds new topics (with the
 name of an ID or something) upon saving a post. It's a custom registerede
 taxonomy.

 I deactivated all plugins and put these lines of code in functions.php of
 Twentynineteen, - and the bug is still reproducable:


 {{{
 /**
  * Disable regular editor
  */
 function life_init_remove_support(){
         remove_post_type_support( 'page', 'editor');
         remove_post_type_support( 'post', 'editor');
 }
 add_action('init', 'foobar_init_remove_support', 100 );


 // Register Custom Taxonomy
 function foobar_learning_packages_taxonomy() {

         $topic_labels = array(
                 'name'                       => _x( 'Topics', 'Taxonomy
 General Name', 'foobar_lang' ),
                 'singular_name'              => _x( 'Topic', 'Taxonomy
 Singular Name', 'foobar_lang' ),
                 'menu_name'                  => __( 'Topics',
