TcxPageControl - The component editor does not take into consideration the Properties.TabSheetClass property value when creating new pages

The component editor registered for TcxPageControl does not take in consideration the value of Properties.TabSheetClass.
This is giving me problems, because I am writing a page control descendant that uses also a TcxTabSheet descendant for its pages, and, at design time, the component editor insists in creating pages of the parent class.

I managed to correct this problem by fixing the component editor this way (the commented lines are the original lines I changed)

Delphi
procedure TcxPageControlComponentEditor.AddPage;  
var  
  Page: TcxTabSheet;  
begin  
  Page :=  GetPageControl.Properties.TabSheetClass.Create(Designer.GetRoot);  
  // Page := TcxTabSheet.Create(Designer.GetRoot);  
  Page.Name := Designer.UniqueName(page.ClassName);  
  //Page.Name := Designer.UniqueName(TcxTabSheet.ClassName);  

  Page.PageControl := PageControl;  
  Page.ImageIndex := Page.TabIndex;  
  PageControl.ActivePage := Page;  
  Designer.SelectComponent(Page);  
end;  

Could you please verify this and add it to the official sources?

thank you,
