It works here but i have different code in the meantime. We're in a 
transition to an lmtx version of the font handler. In lmtx we need to do 
a bit more checking when we are in in compact font mode so it might be 
that there is temporary loss of some functionality. In principle mkiv 
and lmtx should do the same as there is no real change in logic.)

I'll push an update later today,
