Additional Information
There is about a 2-meter difference in the rounding error when comparing the two JSON texts using WinMerge. For a more accurate comparison use the GeometryEngine.Equals() method. Refer to https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Geometry.GeometryEngine.Equals.html for more info. As mentioned in the API Reference, the IsEqual(Geometry) method provides the strictest comparison of two geometries to ensure that they are identical. For a slightly more relaxed comparison, such as in this case where there is a minor precision difference, use GeometryEngine.Equals. Adjusting tolerance can get the desired results. For example, in the reproducer JSON, using the GeometryEngine.Equals method and increasing the tolerance to 2.5 returns 'true' for geometry comparison.Steps to Reproduce
