Why ScaleTransform Transition no work?

[kyuranger]

Here is Xaml:

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
        x:Class="AvaloniaApplication3.MainWindow"
        Title="AvaloniaApplication3">
	<Border HorizontalAlignment="Left" Height="5" Width="500" Name="B" Background="Red" RenderTransformOrigin="0,0.5">
		<Border.RenderTransform>
			<ScaleTransform ScaleX="0" ScaleY="1" />
		</Border.RenderTransform>
		<Border.Transitions>
			<Transitions>
				<TransformOperationsTransition Property="RenderTransform" Duration="0:0:3"/>
			</Transitions>
		</Border.Transitions>
	</Border>
</Window>

And here is the code:

using Avalonia.Controls;
using Avalonia.Media;

namespace AvaloniaApplication3
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.Loaded += MainWindow_Loaded;
        }

        private void MainWindow_Loaded(object? sender, Avalonia.Interactivity.RoutedEventArgs e)
        {
            var i = B.RenderTransform as ScaleTransform;
            if (i is { })
            {
                i.ScaleX = 0.5;
            }
        }
    }
}

I have declared the ScaleTransform in XAML already while the scale animation never works. The version I am using is 11.0.4. What's wrong with it?

It seems that this question has been listed as a BUG before. I'm sorry that I asked it again. ##12938
