Why does the StyledProperty in Panel not follow the StyledProperty changes in Template Control

[AscendLiu]

Code

...
SensorBox : TemplatedControl 
{

    public SensorRegionNumber SensorRegionNumber
    {
        get => GetValue(SensorRegionNumberProperty);
        set => SetValue(SensorRegionNumberProperty, value);
    }
    public static readonly StyledProperty<SensorRegionNumber> SensorRegionNumberProperty =
        AvaloniaProperty.Register<SensorBox, SensorRegionNumber>(nameof(SensorRegionNumber),SensorRegionNumber._8x8);

    protected override void OnPropertyChanged(AvaloniaPropertyChangedEventArgs change)
    {
        base.OnPropertyChanged(change);
        if (change.Property == SensorRegionNumberProperty)
        {
            Console.WriteLine($"Box changed:{change.GetNewValue<SensorRegionNumber>()}"); // OK
        }
    }

}

Panel:

public class SensorPanel : Panel

It has been discussed here. #17553

That's indeed the same problem, sorry I couldn't find it when I searched. I'm using version 11.2.0, and there are no compilation issues except for no errors. According to the description in #17553, it was successfully resolved using version 11.2.1. Thank you
