Italic correction behaviour is odd

Italic correction behaviour is odd

[Henri Menke]

Dear list,

why are italic corrections in the MWE below not inserted according to the rules stated in the new font manual?  See comments in the code for details.  I can reproduce the issue with TL2016 and latest beta.

Cheers, Henri

\definefontfeature
  [default]
  [default]
  [itlc=yes]

\setupitaliccorrection[text]

\enabletrackers[typesetters.italics]

\starttext
{\it beef} beer % seems to be fine

{\it beef} \hbox{beer} % why is correction inserted here?  It's a box

{\it beef}? % correction missing

{\it beef\/}? % adding `global' flag inserts correction here

{\it beef\normalitaliccorrection}? % works always with itlc=yes
\stoptext

you can test with

local function okay(data,current,font,prevchar,previtalic,char,what)
     if data then -- remove the not

in typo-itc.lua
