The problem here is that the user is using the single field block to display their woocommerce product description field but their formatting is being stripped out.
Solution:
The Woocommerce product field is a modified version of the default Post Excerpt field and Woocommerce has a special API to handle this internally. When displaying this field with our View Blocks it will retrieve the field's value using the wordpress default excerpt API. This means that the formatting will be stripped.
To work around this you can create a WYSIWYG custom field and then place your product description in this field.
