Bug: Inconsistency in Layer Order when Copying and Pasting with Offset Fills

When copying and pasting a group that contains areas with offset fills and other objects the visual order of fill vs the objects can be changed. When the area is offset to the same layer as the object the object will appear on top if placed second. However, after copying and pasting, the pasted group will have the area move to the top. See attached image.

Area is on layer 4 with a -3 offset. Tree and pebbles are on layer 1. So all are effectively on the same layer.

Original (bottom) has tree and pebbles on top. Pasted version (top) has area on top, covering other objects. No path/object settings have changed.
