Window with ExtendClientAreaToDecorationsHint="True" cannot be moved in 0.10.5

Describe the bug In version 0.10.3 moving window with flag ExtendClientAreaToDecorationsHint = “True” worked fine. I also checked version 0.10.4 and there it works too. After upgrading package to version 0.10.5 window is stuck in place and cannot be moved.

To Reproduce

1. Create avalonia project (mine is creating in vesrion 0.10.3 by default and im and creating MVVM template).
2. Upgrade Avalonia packages to version 0.10.5 (Avalonia, Avalonia.Desktop, Avalonia.Diagnostics, Avalonia.ReactiveUI).
3. In MainWindow.axaml add flag ExtendClientAreaToDecorationsHint="True" in Window tag. Xaml is looking like this

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:vm="using:AvaloniaMoveTest.ViewModels"
        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="AvaloniaMoveTest.Views.MainWindow"
        Icon="/Assets/avalonia-logo.ico"
        Title="AvaloniaMoveTest"
	ExtendClientAreaToDecorationsHint="True">

    <Design.DataContext>
        <vm:MainWindowViewModel/>
    </Design.DataContext>

    <TextBlock Text="{Binding Greeting}" HorizontalAlignment="Center" VerticalAlignment="Center"/>

</Window>

1. Build project and run.
2. Window cannot be moved.

Expected behavior Should be possible to move window with mouse.

Desktop (please complete the following information):

• OS: Window
• Version: 20H2 (19042.985)

I was also affected by the issue in 0.10.18. Adding margin to the root control helped to restore the draggable header.

Is it so by design now? Documentation should probably be updated to explain this caveat. How should I go about adding non-interactive elements to the header area without affecting the window draggability?

Update: Setting ExtendClientAreaChromeHints="PreferSystemChrome" on my Window as found there had no observable effect. Setting CanResize explicitly to any value has no observable effect.

Update 2: Using IsHitTestVisible allows to have controls in the header area without affecting the draggability.

Confirmed as fixed in 0.10.6, closeable?
