No search results when map is extremely zoomed out

[mfgumban]

When the map view is zoomed far out, ML will respond with zero search results (every map zoom/pan makes a search request).

The bounding box being passed is based on the current map viewport, which in said state can go beyond the values of 90°/180°:

{
  "geospatial-constraint-query": {
    "constraint-name": "Location",
    "box": [
      {        
        "south": -153.31842955933732,
        "west": -263.51118227807473,
        "north": 196.83694800929285,
        "east": 282.62983484645946
      }
    ]
  }
}

Check and limit the viewport values before making the request to avoid this issue.
