[Therion] preview above/below in elevation maps?

[Xavier Pennec]

Does anyone has experience with preview above/below in elevation maps?

I use it quite often in plan maps, with the expected behavior, but when 
I try it in an elevation map, the "previewed" map does not appear at all 
in my pdf neither with below or above.   I am wondering if I missed 
something in the intended behavior or if there is a bug in my layouts 
(although it does not work either if I don't load them).

Thanks for your insights

Xavier
