MaxAutoSizeHint on Windows limit PopupRoot to smaller width ou height when use multiple screens and default screen have lower resolution

[douglaseds9]

Describe the bug

When using multiple screens and the default screen has a smaller width or height, the PopupRoot is limited to a smaller width or height. Although the expected behavior is MaxWidth and MaxHeight as the sum of the width and the sum of the height of the screens,
respectively, or something less limiting.

Avalonia/src/Windows/Avalonia.Win32/PopupImpl.cs

Lines 30 to 46 in 98a388d

	public override Size MaxAutoSizeHint
	{
	get
	{
	if (_maxAutoSize is null)
	{
	var screen = base.Screen.ScreenFromHwnd(Hwnd, UnmanagedMethods.MONITOR.MONITOR_DEFAULTTONEAREST);
	if (screen is not null)
	{
	_maxAutoSize = screen.WorkingArea.ToRect(RenderScaling).Size;
	}
	}
	return _maxAutoSize ?? Size.Infinity;
	}
	}

To Reproduce

1. Create a app with a Flyout;
2. Run on multiple screens system with the lower resolution screen as default;
3. Try to Flyout Width greater than smaller screen width.

Expected behavior

The Width of Flyout is not limited to a Width smaller than the Width of Window..

Can you please provide a minimal reproducible version of the XAML you're using to create the flyout?
I cannot replicate the behaviour from the steps you have provided.
