Visibility scan grid, pin result panels fail to load after the first click

Steps to reproduce

1. Open a completed visibility scan in grid view.

2. Click any pin. The results panel opens and loads correctly.

3. Close the panel and click a different pin.

4. Refresh the page and click the same pin again.

Expected
Every pin opens a panel with the top 20 results for that search point, matching the rank shown on the pin.

Actual :
The first pin clicked after page load returns results. Subsequent pins open an empty panel that never loads. After a refresh, a previously empty pin may load correctly while others stay empty. Which pins work seems random and changes between refreshes.
