[Bug]: Incorrect background paint reported by getInfo("map")

[kwvanderlinde]

Describe the Bug

The background paint returned by getInfo("map") or getInfo("zone") is actually the grid color.

To Reproduce

1. Create a new map with a black background.
2. Set the map grid colour to white.
3. Type [r: json.get(getInfo("map"), "background paint")] into chat. It will return #ffffffff, the colour of the grid.
4. Change the grid colour to any other colour.
5. Run [r: json.get(getInfo("map"), "background paint")] again. It will return the new grid colour.

Expected Behaviour

The background colour of the map should be returned. In the provided example, it should return #ff000000.
