Duplicate rendering of paragraphs in EPiserver.Forms 5.6.0

Hello, 

there was a defect introduced in EPiserver Forms 5.6.0 causing elements of the type Rich text (with placeholders) to render twice.

Steps to reproduce:

EPiServer.CMS 12.26.1
EPiServer.Forms 5.6.0
EPiServer.Forms.Core 5.6.0
EPiServer.Forms.UI 5.6.0

1. Create a new Form.
2. Add a field of type Rich text (with placeholders).
3. Enter the text Test.
4. Use the form on a published page.
5. Publish the form.
6. View the published page.
7. Test is rendered twice

Notice that the rendering works as expected when inside the edit on page -window

<div class="Form__Element FormParagraphText Form__Element--NonData" data-f-element-name="__field_243642" data-f-element-nondata="">        <div id="6beb4576-e086-4d0e-b180-bb1909b71038"><p>Test</p>        </div><div id="6beb4576-e086-4d0e-b180-bb1909b71038__OriginalText" class="Form__Original__ParagraphText"><p>Test</p>        </div></div>
