Polygon.toJson() does not serialize double values with precisions over 8 digits properly

When I covert the lat, lan values below to polygon and convert the polygon to json using toJson method it removes some digits from lat, lan values(it takes just 6 - 7 digits).

Here is the json output
{
"type": "Polygon",
"coordinates": [
[
[
-93.1640625,
34.8859309
],
[
-82.265625,
-15.6230368
],
[
-35.15625,
-22.9179229
],
[
18.28125,
-7.0136679
],
[
2.4609375,
45.5832898
],
[
-64.3359375,
54.3677585
],
[
-93.1640625,
34.8859309
]
]
]
}

it should construct json correctly. could not use the library

从 Polygon.toJson() 开始，跟踪多边形的坐标值是如何序列化的。使用报告中的纬度和经度值复现该问题，然后验证生成的 JSON 是否保留了报告中的精度。payload 未指定源文件或测试，因此需要在 repository 中找到它们。
