How can I disable automatic tag substitution in widgets in Gutenberg in the "arbitrary HTML" block?

Question

WordPress

I insert the HTML code on the widget page into the "arbitrary HTML" block.

Gutenberg or WP substitute their tags into the HTML I write after publishing or refreshing the page:


I tried the following solutions ( did not help ):

/**
 * Отключаем автоформатирование в редакторе WP
 */
remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_widget', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );
remove_filter( 'comment_text', 'wpautop' );

Also tested on a clean theme, Twenty Twenty-One, still the same problems.. inserted the following code:

<h5 class="text-start pb-3">Способы связи</h5>
<div class="phone mb-3 d-flex align-items-center mb-2">
    <img class="no-soc" alt="Телефон" src="/wp-content/themes/rgTheme/assets/img/icon-phone.svg">
    <p class="mb-0">[site_info phone]</p>
</div>
