When trying to use the new row I get Binding Errors when using the Office2019 theme and the new row is a visually empty.
The Binding errors are:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.GridViewDataControl', AncestorLevel='1''. BindingExpression:Path=GridViewNewRowContent; DataItem=null; target element is 'ContentPresenter' (Name=''); target property is 'Content' (type 'Object')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.GridViewDataControl', AncestorLevel='1''. BindingExpression:Path=GridViewNewRowContentTemplate; DataItem=null; target element is 'ContentPresenter' (Name=''); target property is 'ContentTemplate' (type 'DataTemplate')

When using the Office2013 theme everything works as expected. If I disable row virtualization the Office2019 theme works as expected.
What do I need to change to get the Office2019 theme working with vivirtualization ?
