GeoLocation issues on 10.3.3

It appears we need both keys present for iOS 11+ to work properly - even though a when-in-use request is made:

<key>NSLocationWhenInUseUsageDescription</key>
<string>This helps you to set your current location when searching for...</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key> 
<string>This helps you to set your current location when searching for...</string>

The following still spawns an always-use request and not when-in-use

geoLocation = new Geolocation();
geoLocation.locationAlwaysUsePermission = false;//this should be false by default
geoLocation.requestPermission();

I'm also seeing two events after someone clicks "Yes" to the Apple prompt.  The first is PermissionStatus.GRANTED followed immediately by PermissionStatus.DENIED

Note - this is only on iOS 10.3.3 (and lower) - 11+ appears to be working as expected by showing the in-use prompt and kicking out PermissionStatus.ONLY_WHEN_IN_USE events.
