Собственно для чего это. Если надо разместить, к примеру, микроразметку в визуальном редакторе, то после ставок кода
<span itemprop="streetAddress">номер дома, улица</span> <span itemprop="postalCode">почтовый индекс</span> <span itemprop="addressLocality">город, страна</span>
на выходе получим
номер дома, улица почтовый индекс город, страна
то есть, редактор сделал валидацию кода и очистил, по его мнению лишний код, а нам такое не нужно.
Как с этим бороться
Вставляем в файл функции темы (functions.php), следующий код
function my_adds_alls_elements($init) {
if(current_user_can('unfiltered_html')) {
$init['extended_valid_elements'] = 'span[*],div[*]';
}
return $init;
}
add_filter('tiny_mce_before_init', 'my_adds_alls_elements', 20);
В данном случае убираю валидацию с тегов span и div.
div так же очищается если не отключить валидацию, а он часто нужен для микроразметки
Пример
номер дома, улица
почтовый индекс
город, страна
почтовый индекс
город, страна
Использую классический редактор

span тегов в визуальном редакторе (WordPress) — Грабли <Loved it!
I apologise, but, in my opinion, you are not right. I can defend the position. Write to me in PM, we will communicate.
Данный код — рабочий. Я использовал вордпресс 5.2.2 и классический редактор вместо нового блочно редактора.
Для демонстрации, что все-таки код рабочий, на странице разместил в примере кусок со span, где прописал атрибуты, и добавил в эту функцию в функции темы.
Возможно у вас есть другой вариант решения данной проблемы

Woah! I’m really digging the template/theme of this
blog. It’s simple, yet effective. A lot of times it’s very difficult to
get that «perfect balance» between usability and visual
appeal. I must say you’ve done a very good job with this.
In addition, the blog loads very fast for me on Firefox.
Exceptional Blog!
