So, you mean that the code should use the font of the symbol and not the 
font of the environment? That makes perfect sense...

Congrats, Enrico.

Instead of returning the font of the symbol (which is a weird side 
effect), it would be possible to introduce mathedSymbolFont(). Or to 
move this mathedSymbolXX stuff to members of latexkeys.

But the important part is done :)
