[NTG-context] LuaTeX + microtype: Small Caps vs. Letter Spacing

Hi everyone,

I'm happy to see that by now almost all of microtype's features are 
available in Lua, almost like in the old days. There's one thing that 
seems a bit strange, though:

While I have no trouble applying letter spacing using \textls or 
\lsstyle to regular, italic, or bold text, I can't get it to work on 
small caps. What's even stranger: while this problem occurs with all 
fonts I've tried, it does /not/ occur when I don't specify a font at 
all. Consider the example below. The only way to get the correct output, 
with spaced small caps, is to deactivate the \setmainfont line -- which 
obviously isn't what you'd want :)

Any hints are appreciated; chances are I just have to add a thing here 
or there.


\setmainfont{Minion Pro}%or TeX Gyre Termes, or Latin Modern Roman...
stealing sheep\par
\textls{stealing sheep}\par
\textsc{stealing sheep}\par
\textls{\textit{stealing sheep}}\par
\textls{\textbf{stealing sheep}}\par
\textls{\textsc{stealing sheep}}
