Fix popup issue (#1368)

## Launch Checklist

When clicking the map to create a popup and then clicking on the map
again without closing the popup something breaks in react.
This PR fixes it.

Steps to reproduce:
1. Click on the map
2. Click on the map but not on the popup

The following malformed popup appears:
Before:
<img width="610" height="626" alt="image"
src="https://github.com/user-attachments/assets/99cbdf9a-0b3c-436d-ab13-f219ee3c6e75"
/>

After - popup looks good.
<img width="610" height="626" alt="image"
src="https://github.com/user-attachments/assets/6b379c0d-cbbf-40ed-916d-3cc10eaf4410"
/>

I couldn't make cypress reproduce the exact scenario, but I added some
basic tests for popups.
