[NTG-context] compact fonts, fake slanted and \definefallbackfamily (LMTX only)

Dear list, I have the following sample: \enableexperiments[fonts.compact] \definefallbackfamily [mainface][rm][Dejavu Sans] [sl={style:regular, features:slanted},preset=range:greek] \definefontfamily [mainface][rm][Latin Modern Sans] %[sl={style:regular, features:slanted}] \setupbodyfont [mainface] \starttext αβγ9 some word others\\ \sl αβγ9 some word others \stoptext The only way to get slanted Greek is either with disabled compact fonts, or with fake slanted added to \definefontfamily. I’m experiencing this with LMTX only (MkIV is fine). I’m using current latest (2025.02.07 20:46). Could anyone confirm the issue? Many thanks for your help, Pablo
