When the Target version of the UWP project is Windows 1809, RadButton raises the following exception:
System.ArgumentException: Value does not fall within the expected range.
Padding and HorizontalContentAlignment are not properly applied when Image is used.
If you have set the HorizontalContentAlignment to some other value (End, Start) and you run the application in Release mode in UWP -> the value is reset to center.
Setting the padding property does not offset the text of the button in iOS Available in the R2 2018 release.
