Reproduce the issue by scrolling a WPF DataGrid containing a CheckComboBox and observe the selected item disappearing. Start with the CheckComboBoxItem binding reported in the error, especially the PART_SelectAll HorizontalContentAlignment RelativeSource binding; done means the selection remains visible after scrolling without the binding error.
