Describe the bug

I tried to show a computing expression like ((1 + 2) + 3) using a ContentControl and DataTemplates. But error occurred when a DataTemplate contained a child using the same template as itself. As comparison, it works well when the adding expression doen't contains an adding expression as its child.
