Steps to reproduce:
- Make sure you have both Cite and Citoid enabled.
- In VisualEditor, add a citation via the "Cite" dropdown. Add some value and click "apply changes".
- Edit the same citation again.
- With the old sidebar there will be a button to "change reference type" at the bottom of the dialog. (Note: This was broken and fixed via T293280.)
- This button is missing with the new sidebar.
