Steps to replicate the issue:
- Edit a sub-reference in VisualEditor
- Enter a new line in details
What happens?:
- Sub-ref details are displayed in two lines in the reference pop-up
- Reference list doesn't display the new line
- Wikitext shows a new line
- After saving the edit, the new line no longer appears when editing the page again
What should have happened instead?:
- Don't show the new line, matching the behaviour of the reference list (and the page after saving and editing again)
