Omschrijf het probleem / Describe the bug

When you have a WYSIWYG content element as part of a form step with multiple lines/whitespace/linebreaks, the summary page does not display this whitespace but instead appends everything together.

It looks like some newlines are not properly converted to <br> tags, or the WYWIWYG content is stripped from HTML tags.

Stappen om te reproduceren / Steps to reproduce

1. Define form with content field containing blank lines
2. Fill out form
3. Continue to summary page
4. Observe the missing whitespace

Verwacht gedrag / Expected behavior

Whitespace from the WYWIWYG field is displayed in a consistent way in the form designer, step and summary.

The summary page content is rendered as text:

open-forms/src/openforms/submissions/models/submission.py

Line 434 in 268d36e

renderer = Renderer(submission=self, mode=RenderModes.pdf, as_html=False)

Note for posterity: after investigation this was not an issue of rendering the non-HTML version, but having the 'content' component show up in the summary at all.
