[NTG-context] \em issue in MkXL (2024.03.05 11:26)

Dear list, the following latest gets differents results when compiled with MkXL and MkIV (in current latest from 2024.03.05 11:26): \definefontfamily[mainface][rm][TeX Gyre Termes] [features={default, quality}, it={style: regular, features:{default, quality, slanted}}, sl={style: regular, features:{default, quality, slanted}}] \setupbodyfontenvironment [default] [em=italic] \setupbodyfont[mainface] \starttext \startTEXpage[offset=1em] a\\ \em b\\ \em c\\ \em d\\ \stopTEXpage \stoptext LMTX gets b, c and d in slanted form. LuaTeX gets only b and c in slanted form. I think LMTX may have an issue here. Could anyone be so kind to confirm this? Many thanks for your help, Pablo
