Editor.Scrolling.DefaultHorzScrollSize = 0;

DefaultHorzScrollSize Attribute not found in WPF Editor. Scrolling？
Yes, we don’t have this property for WPF, it measures horizontal scrollbar based on a document content. Let me know if it works for you with one of the recent versions (6 or 7) and if so, could you provide a bit more details of in what situations you would need this property?
