When binding an icon through a DataContext, the problem occurs when the DataContext is released Open

Empty
I am using Prism DailogService with ChromelessWindow, ChromelessWindow's Icon I set via Binding, when the window is closed, the DataContext is released, the ChromelessWindow's icon is null at this time, the exception is thrown by the IcoFileSizeSelectorConverter

Empty

This problem can be solved by overriding Window's OnClosed method
