Describe the bug
When changing a URL preview to "Show link preview" and exiting edit mode, the link disappears entirely, leaving unformatted text and removing linebreaks afterwards. Reentering edit mode causes the preview to again be rendered correctly.
This is caused by the newest collectives version and the changes to the URL preview functionality.

To Reproduce
Steps to reproduce the behavior:

1. Write some text and add a URL to it
2. Click on the option 'Show link preview'
3. Notice the function working correctly while still in edit mode
4. Save the page, click on done and the preview disappears
5. Notice that reloading the page does not fix it
6. Notice that returning to edit mode displays the preview again
7. Notice also that switching back to "Text only" causes the original text with the URL behind it to be displayed correctly

Expected behavior
The URL preview should always be rendered correctly.

Screenshots
