Describe the bug

Changing ShowInTaskbar to false after showing the window will hide it in the task switcher on Windows 11(other OSes were not tested).
Well, my feature #18689 #18695 has already been implemented by a bug. What the hell?

To Reproduce

Uncheck the CheckBox.

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        x:Class="Test.MainWindow"
        ShowInTaskbar="{Binding #IsShowInTaskbar.IsChecked}">
        <CheckBox Content="ShowInTaskBar" Name="IsShowInTaskbar" IsChecked="True" />
</Window>

Expected behavior

It should still be visible in task switcher

Avalonia version

11.3.0-beta2

OS

Windows

Additional context

Windows 11 23H2

It seems that a hidden parent window can hide a child window in the task switcher, and that's the original ShowInTaskbar=false 's side effect. But Show() sets the window parent to _parent before showing the window, so it should show correctly.
I think maybe I should change the Show() function's behavior and see what will happen.
I'm not sure if it is a Windows' bug or Avalonia's operations' side effects.
It can be easily solved by re-showing the window, but maybe figureing out its reason is a chance to create a more flexible and light-weight window.
