There is an inconsistency between the values given with the `gsbbox` parameter and the results of the `geosearch` query.
The de-fact bounding box seems to be `180-xmin` to `180-xmax`, rather than `xmin` to `xmax`, where `xmin` and `xmax` are the values used in the `gsbbox` parameter
For example, the results of [a query using a `gsbbox=37.8|-122.3|37.7|-122.4`](https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsbbox=37.8|-122.3|37.7|-122.4&format=json) includes includes a location with `"lon": 57.63055555555555`
```

},
```
Similarly, the results of [a query using `gsbbox=37.8|57.7|37.7|57.6`](https://en.wikipedia.org/w/api.php?action=query&list=geosearch&gsbbox=37.8|57.7|37.7|57.6&format=json) includes a location with `"lon": -122.34194444444444`
```

"lon": -122.34194444444444,

},
```
This may or may not be related to the unconventional coordinate order of `gsbbox` - `ymax|xmax|ymin|xmin`.
