"Also On Top" Support Function is not correct

Hello,

In the current stable version as well as the V2 Alpha, the feature "also on top" within the Support tab is not correctly implemented. I have attached a screenshot illustrating the problem with this feature. In this screenshot I have the gcode visualized within KISSlicer as well as the numerical code supporting my claim.

What is happening is the "top interface" path is offset downward the [Zgap] amount, or in this case, .18mm for some reason. Instead, this Zgap needs to be offset outside of the STL mesh.

My question is: If KISSlicer can recognize when to put interface on top of the part, why does it not offset the gap correctly?

Let me know if I am correct in this assumption or if others have experienced similar. Maybe this is by design? Either way, for single material prints, it is problematic to embed a filament path within the model when the idea is to remove when the print is done.

Thank you,
Justin
