When using WMS in a WebMercatorProjection instead of GeographicProjection user will get the wrong feature position in response. The issue seems to be coming from

cesium/Source/Scene/GetFeatureInfoFormat.js

Lines 88 to 92 in ca8b918

if (defined(feature.geometry) && feature.geometry.type === "Point") {
var longitude = feature.geometry.coordinates[0];
var latitude = feature.geometry.coordinates[1];
featureInfo.position = Cartographic.fromDegrees(longitude, latitude);
}

which incorrectly assumes that point coordinate is in GeographicProjection. Also, the issue that might affect more users is the selection indicator that is wrongly positioned. In some rare cases, it might even fly around as user rotate the globe (see photo below).
Any tips on approach solving this, thinking about passing a tilingScheme or MapProjection instance to GetFeatureInfo.
