Surface series sides (back) drawn incorrctly

[TEh]

The sides in surface series are drawn incorrrectly, specifically the side that should be behind the actual surface is drawn on the foreground blocking part of the surface itself.

This can be seen in your feature demo (All Features->Chart Styles->Extended->Surface->Sides)

Hi TEh,

You are right. I've added it to the defect list to be fixed in future releases (TF02015128).
