[Forminator Pro] Forminator removes HTML from success message

I created a form with an inline message after form submission.
The inline message allows simple HTML markup (bold, ul, … ) – however, upon saving that markup is lost and the message is saved in plain text.

I’ve checked the workflow: The form submits the HTML code correctly. When I check the DB right after updating the form, I can see a plain-text version of my message there. So the HTML markup is lost while saving the form.

Problem seems to be in “forminator/admin/classes/class-admin-ajax.php” in function “save_builder”. In line 460 the function “forminator_sanitize_field()” removes the HTML tags from my message.
