Invalid Html markup for empty field in form

Description

Steps to reproduce

1. Create a new form.
2. Set the Form Title and Form Description to empty.
3. On Views, the form is still rendered as below (it's invalid with a W3 validator):

<h2 class="Form__Title"></h2>
<aside class="Form__Description"></aside>

Expected
Do not render html content if property is empty.

Actual
html content is rendered even though the property is empty.
