I think the right fix is to refresh all font objects that have already
been created.  However, there's currently no way to find them.  At
startup, however, I think only the default face has a font object
assigned to it---that's why I suggested this hack.

Yeah, it's a pretty awful hack, but I don't see a better short-term
solution.
