Confirmed. This is the code translated to Context:

  \definefontfeature[pwid][mode=node,script=latn,language=dflt,pwid=yes]
  \definefontfeature[fwid][mode=node,script=latn,language=dflt,fwid=yes]
  \starttext
    {\definedfont[file:kozminpr6n_regular.otf*pwid]A…B}
    {\definedfont[file:kozminpr6n_regular.otf*fwid]A…B}
  \stoptext

Below is the patch translated for font-otf.lua.

Best
Philipp
