When you enter the HTML code directly, the layout changes depending on the p and br tags that WordPress automatically inserts.
remove_filter( 'the_content', 'wpautop' );
It can be solved by adding the above code. However, this will disable all auto-inserted p and br tags. It is not user-friendly.
This plugin can be partially disabled.
Just enter the part you want to disable in the shortcode.
