Just checking back in on this to say that this still happens with other form plugin shortcodes as well (Mailpoet, Formidable), and only when used in an ACF wysiwyg field. It seems the issue is that BR tags are added below each hidden field in the form, thus creating a bunch of empty lines above and below the form. Again, this does not happen in the native WP editor — only ACF. This happens with any theme I try. Has anyone had any success with fixing this problem?
