Well, at least LyX actually changes the package loading order when math 
fonts are loaded. So, it seems that it could be a bug of LyX.

In any case, it seems that restyle has not been updated for a long time, 
so maybe fixes are unlikely. Hence, LyX has to deal with this in one way 
or another for the time being.
