Describe the bug

When a participant uses the WYSIWYG editor, he always has the possibility of adding images or videos, that later will not be rendered.
Also, an admin faces the same issue, when attempts to use the WYSIWYG on a field that does not render the images of videos

To Reproduce

1. Visit Admin Panel
2. Go to Assemblies, click edit on one assembly
3. Observe the Video and Image icons
4. Fill in Closing date with a date and also "Closing date reason" ( add a video)
5. Save
6. Visit public interface
7. See Closing date reason in the sidebar, without any video being rendered

Expected behavior

When using WYSIWYG, the admin should only be allowed to add content that can be rendered.
