RSRP-472887: "To property with backing field" is not available for property with arrow getter and setter

Write the following code:

using System.ComponentModel;
using System.Runtime.CompilerServices;
using WpfApplication1.Annotations;

namespace WpfApplication1
{
    public class Class1 : INotifyPropertyChanged
    {
        private int _backedProp;
        private int _backedProp2;

        public int BackedProp
        {
            get { return _backedProp; }
            set { _backedProp = value; }
        }

        public int BackedProp2
        {
            get => _backedProp2;
            set => _backedProp2 = value;
        }

        public event PropertyChangedEventHandler PropertyChanged;

        [NotifyPropertyChangedInvocator]
        protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

Then, select BackedProp and press Alt-Enter: the action "To property with change notification" will be available (OK).

Select BackedProp2 and press Alt-Enter again: the action "To property with change notification" is not available.
