Description
**mapbox-gl-js version**: 2.6.0-beta.2
**browser**:Any
### Steps to Trigger Behavior
1. Use `http://localhost:9966/debug/heatmap.html`
2. Use box zoom or fit screen coordinates with a slight pitch
### Behavior
- These APIs make use of the FreeCamera interface, which isn't supported by non-mercator projections
- A warning is issued but the behavior isn't fully a no-op

Research direction
Start with debug/heatmap.html and the box-zoom and fit-screen-coordinates entry points, then trace how they use the FreeCamera interface under non-mercator projections. Reproduce the issue with a slight pitch and verify that the warning and resulting behavior are consistent with FreeCamera being unsupported.
