FloatingBlock invalid

[MCcber]

Describe the bug

• Under .NET8
• Nuget Version is 3.5.1,Name is HandyControl
• System Version is Win11 22H2 22621.3447

Available when handyControl:FloatingBlock.Content is set, invalid when ContentTemplate is set

Steps to reproduce the bug

After writing the following code in the WPF program and starting debugging, the FloatingBlock fails.

<Button
    Width="180"
    Margin="0,10,0,0"
    handyControl:FloatingBlock.Duration="0:0:1"
    handyControl:FloatingBlock.ToX="50"
    handyControl:FloatingBlock.ToY="-80"
    handyControl:FloatingBlock.VerticalOffset="-20"
    handyControl:IconElement.Geometry="{StaticResource ThumbsUpGeometry}">
    <handyControl:FloatingBlock.ContentTemplate>
        <DataTemplate>
            <Path
                Width="16"
                Height="16"
                Data="{StaticResource ThumbsUpGeometry}"
                Fill="{DynamicResource DangerBrush}" />
        </DataTemplate>
    </handyControl:FloatingBlock.ContentTemplate>
</Button>```

### Expected behavior

Theoretically, after writing the above code and starting debugging, your thumb should fly upward when you click the button. In fact, this does not happen.
