Geo Code Lat Long Mismatch from request

Thanks for the awesome project.
Stumbled into an issue where the request lat long differs from the response

Implementation

export const getAddressFromLatLon = (lat, lon) => {
  console.log("Sent Lat long");
  console.log("Lat : ", lat);
  console.log("Lng : ", lon);
  return new Promise(function (resolve, reject) {
    geocoder.reverse({ lat: lat, lon: lon }, function (err, res) {
      if (err) {
        resolve("");
      } else {
        console.log("Reverse Gocoder Response: ", res);
        let city = res[0].city;
        let formattedAddress = res[0].formattedAddress;
        let addressData = res[0].extra;
        let sublocality_level_1 = addressData.sublocality_level_1;
        let route = addressData.route;
        let premise = addressData.premise;
        let subpremise = addressData.subpremise;
        let bestAddress = "";

        if (route !== null) {
          bestAddress =
            route +
            (sublocality_level_1 !== null ? ", " + sublocality_level_1 : "") +
            (premise !== null ? ", " + premise : "") +
            (subpremise !== null ? ", " + subpremise : "") +
            (city !== null ? ", " + city : "");
        } else {
          bestAddress =
            formattedAddress.toString().split(",")[0] +
            (sublocality_level_1 !== null ? ", " + sublocality_level_1 : "") +
            (premise !== null ? ", " + premise : "") +
            (subpremise !== null ? ", " + subpremise : "") +
            (city !== null ? ", " + city : "");
        }
        console.log("Best Address Location :", bestAddress);
        resolve(bestAddress);
      }
    });
  });
};

Request Lat Longs

Sent Lat long
Lat :  27.6720744
Lng :  85.42810229999999

Response
Reverse Gocoder Response:

 [
  {
    formattedAddress: 'Unnamed Road, Bhaktapur 44800, Nepal',
    latitude: 27.6721454,
    longitude: 85.42813939999999,
    extra: {
      googlePlaceId: 'ChIJIwbrk68a6zkR3k9u7g4Y7Ug',
      confidence: 0.7,
      premise: null,
      subpremise: null,
      neighborhood: 'Bhaktapur',
      establishment: null,
      sublocality_level_1: null,
      route: null
    },
    administrativeLevels: {
      level2long: 'Bagmati',
      level2short: 'Bagmati',
      level1long: 'Central Development Region',
      level1short: 'Central Development Region'
    },
    streetName: 'Unnamed Road',
    city: 'Bhaktapur',
    country: 'Nepal',
    countryCode: 'NP',
    zipcode: '44800',
    provider: 'google'
  }
]

The response returned the lat long which is different from the request.
