Description
When `globe` projection is used the following snippets yield inconsistent behavior when compared to `mercator` projection:
### `getBounds` and `cameraForBounds`:
```
const c = map.cameraForBounds(map.getBounds());
map.easeTo(c);
```

The returned camera transform should remain the same similar to when `mercator` is in use:

### `fitScreenCoordinates`:
```
map.fitScreenCoordinates([0, 0], [map.transform.width, map.transform.height], map.getBearing())
```

### `fitBounds`:
```
map.fitBounds(map.getBounds());
```

### `boxZoom`:

Research direction
Start by reproducing the globe-projection cases for getBounds, cameraForBounds, fitScreenCoordinates, fitBounds, and boxZoom using the snippets and recordings in the issue, then trace their camera and projection handling. Done means these operations preserve the expected camera behavior consistently with mercator, with regression coverage for the reported cases.
