1. Open up the Settings app.
2. Scroll down to Safari.
3. Tap on Advanced.
4. Tap on Advanced Tracking and Fingerprinting Protection.
5. Enable for "All Browsing." or keep it on "Private Browsing."

B. Open a mapbox demo with 3D terrain in safari

1. Open Safari in either Private or Normal (depending on your 'Advanced Tracking and Fingerprinting Protection' settings)
2. Navigate to a 3d enabled mapbox map, example: https://docs.mapbox.com/mapbox-gl-js/example/add-terrain/

### Link to Demonstration

Any map with 3d terrain, example: https://docs.mapbox.com/mapbox-gl-js/example/add-terrain/

### Expected Behavior

### Actual Behavior

Start with the add-terrain demo in Safari on iOS 17.0, using the reported Advanced Tracking and Fingerprinting Protection settings, and compare it with normal browsing. Trace the 3D terrain rendering path and determine whether the demo reliably renders terrain under both settings; verify the result on the linked example and a comparable 3D map.
