[NTG-context] Math functions not typeset inside MetaPost

Hi Hans,

[I am sending this again since the previous mails regarding were sent during 
the weekend].

I am on the most recent upload of LMTX [2022.04.15 20:20]. However, when I try 
to use math functions inside MetaPost strings, the function is not typeset 
correctly. Please consider the following MWE:

    draw textext("\m{\max_i x_i}");

which produces the output attached here as an image. Instead of the mfunction 
maxᵢ xᵢ 
some form of the string mathfunctionhandlelabel is typeset.

I tried to inspect \math_function_handle_label [math-ini] and also mp-mlib and 
mlib-pps but could not figure out what is going wrong. I wonder if there is a 
backslash missing somewhere. I am a little worried since I use MetaFun in 
conjunction with maths and could not figure out what the issue is.

Please see the original post by Dalyoung here:

Please advise.

Thank you,
