How to format the Extended part of a post?

Question

Web development

Good afternoon, dear ones.
Faced the following problem:
If you display the content of the post through
the_content();
then everything is in order, all html tags are present. But my task is to split the post into text before more and after. Accordingly, I use the get_extended() function. But when I try to display what's after more, the text is solid, without tags (even p).
I do it like this:

global $post;
$post_parts = get_extended($post->post_content);
echo $post_parts['extended'];

If we use the_content() then when viewing with the developer tool we see the following lines:

<p>Первая строка</p>
<p>Вторая строка</p>

And if so, as I described above, then it turns out:
Первая строка Вторая строка

Try using instead

echo apply_filters( 'the_content', $post_parts['extended'] );
