The issue is the 12x20 font is stored inside Espruino as if it was a custom font. When a custom font is loaded, all that's stored in Graphics is the data for the font - so it's pretty much impossible to figure out which function was called to get that data :(
Potentially we could also store the font name in Graphics, but that's not trivial due to restrictions on how many arguments built-in functions can have :(
