For reproduction in context, the code
\starttext
ff\discretionary{l}{}{l}
\stoptext
currently produces a single `fl` ligature instead of `ffl`.
Interesting that you didn't see those lines, maybe we have different versions?
The patched line is line 844 in the file `font-ots.lua` of ConTeXt beta, updated today.
Best regards
Marcel
