Bug report: CyberChef 'Show on Map' Function Displays Grey Screen Instead of Map

**Describe the bug**
When using the "Show on map" function in CyberChef ('Zoom level': 13, 'Input Format': Auto, 'Input Delimiter': Auto) with the input coordinates 45.693147, 11.880739, the output panel displays the location bookmark, but instead of the map, a grey screen appears.

**To Reproduce**
Steps to reproduce the issue:
1. Open the link: "https://gchq.github.io/CyberChef/#recipe=Show_on_map(13,'Auto','Auto')&input=NDUuNjkzMTQ3LCAxMS44ODA3Mzk".
2. Check the "Output" panel.
3. Notice that while the location is marked, the map does not render correctly (grey screen instead).

**Expected behaviour**
The "Output" panel should display a map with the indicated location instead of a grey background.

**Screenshots**

**Desktop (if relevant, please complete the following information):**
- OS: Windows 10 Pro 22H2 64 bit
- Browser: Firefox desktop 138.0.4 (64 bit)
- CyberChef version: 10.19.4

**Additional context**
This may be a rendering issue with the map or a failure in loading geographic data.
The problem persists across different coordinates.

Reproduce the issue using the provided CyberChef link and inspect the Show on map operation's Output panel. Trace why the map renders as a grey screen across different coordinates; done means the indicated location displays as a functioning map instead of a grey background.
