Navigator.BackAsync exception when getting back from modal to another modal

[Mateusz-Nejman]

Hi! I have some modals and for one case I have to open one modal from another. It work fine, but when I use Navigator.BackAsync, I'm getting exception:
The control Pixed.Application.Windows.PaletteWindow (Content = DockPanel) already has a visual parent AvaloniaInside.Shell.StackContentView (Name = PART_Modal) while trying to add it as a child of AvaloniaInside.Shell.StackContentView (Name = PART_ContentView).'
PaletteWindow is a parent modal. Exception is thrown in StackContentView::PushViewAsync#L64. I locally added catch to try/finally for ignoring this exception and it works, but its temporary workaround.

Hello @Mateusz-Nejman
Thanks for reporting the error. I can see line above there is a check to remove and add again the control if already has a parent.
It can help, if you can provide an real example or solution that I can run and debug.
Thanks.
