1. Navigate to:
   https://www.simonyates.ca/perceptual-design-system
2. Save the page using the Zotero Connector.
3. Confirm that the saved snapshot is correct.
4. Without hard-reloading the browser tab, navigate within the SPA to another page using normal client-side navigation.
   Example:
   https://www.simonyates.ca/studies/pie-chart-bezier-curves
5. Save the second page using the Zotero Connector.
6. Open the saved item in Zotero and inspect the snapshot attachment.
