I use $\sin \theta$ and $\cos \theta$ behave differently in text and in

It works well sometime before but it doesn’t in metafun now. What is wrong in my example?
Thank you for reading. Best regards,

Here is a MWE.
\startbuffer[pointCircle] numeric u; u:=1cm; pair A,B,C; draw fullcircle scaled 4u; A := dir(25)*2u; label.top(textext("$P=(\cos\theta, \sin\theta)$"), A); B := dir(-25)*2u; label.bot(textext("$Q=(\cos(-\theta), \sin(-\theta))$"), B); C := (xpart A, 0); label.lrt(textext("$A$"), C); label(textext("$O$"), origin); \stopbuffer \starttext I'd like use $\sin$ and $\cos$ in the metafun. But it shows strange text instead of $\sin$ and $\cos$.
\processMPbuffer[pointCircle]
\stoptext
Hi Hans and Mikael (and others on the list), I can confirm that even with the newest LMTX [2022.04.15 20:20] the above might actually be a bug. mfunctions inside MP strings are not properly rendred. A tiny MWE: \starttext \startMPcode draw textext("\m{\max_i x_i}"); \stopMPcode \stoptext Could trace it down to '\math_function_handle_label' [math-ini] but not sure what MP is doing. Also looked into mp-mlib, mlib-pps but could not figure it out. I request you to kindly look into it. Thanks, Sreeram
