[Resolved] HTML comment in GeneratePress?

Hi. When I code in the content area and use HTML comment like this <!– comment –> my child div is moved down as if there is a text line before the child div:

<div>   
                           <!-- This is a comment -->
                           <div></div>
</div>

Text “This is a comment” is not visible, but it occupies the space.
Margin: 0; padding: 0; don’t help. Only removing this comment removes an empty space.
When I test the code in CODEPEN everything is OK.
How can I comment on my code in GeneratePress?
Thanks.
