[NTG-context] ConTeXt inserts additional dots for Iosevka font

Hi, ConTeXt has some issues with the character variant features of the Iosevka font available at https://github.com/be5invis/Iosevka/releases/download/v10.1.1/super-ttc-iose... E.g. the following document \definefontfeature [default:test] [default] [cv36=2,cv26=6] \definefont [SomeFont] [name:iosevka*default:test] \starttext \SomeFont I live in a dot-heavy world. \stoptext has six dots instead of one dot over each "i". Tests with multiple other font shapers and inspection of the font file confirmed that this is not intentional behavior. Could you take a look at that? (Based on a luotfload bug report at https://github.com/latex3/luaotfload/issues/202) Best regards, Marcel
