[NTG-context] Notation of the first derivative in mathematical mode (lmtx)

Hello, I replaced the context engine with the lmtx engine but I find that the derivative symbol is too high regardless of the font used. I mainly use modern and pagella because I type many texts using mathematics: can we correct this problem, Thanks for your help.
