Steps to reproduce
- Visit my sandbox page
- Edit the "There are known knowns" section using the 2017 VisualWikitext editor (Note: Don't use the 'Edit source' in the top of the page. Use the 'Edit source' link near the section heading)
- Review your changes as a VisualDiff
Every other section is shown as deleted in the VisualDiff along with the change done to the section even though that is not the case.
Only the change done to the section should be shown.
