Steps to understand:
- Edit an existing article, and change the contents of a <ref>.
- Before saving, check the visual diff. See:
- The ref number (the little blue clicky number) is highlighted.
- The new text displayed.
- The old text has vanished without a trace.
- Save/Publish your change.
- After saving, go to the history page and check the visual diff. See:
- The old text is displayed in red strikethrough.
- The new text is displayed in green (i.e., for insertion).
Expected:
It's the same edit. These diffs should match.
