Thanks for the recipe.

This seems to be a bug in internal-set-lisp-face-attribute that is
specific to the :inherit attribute.  When I try your recipe with other
attributes, like :foreground or :slant, everything works as expected.
(A good face to try this is `fringe': when it changes, you see the
effect immediately.)

Likewise: try with something other than :inherit, it works as
advertised.

I'll look into the problem with :inherit when I have time, unless
someone beats me to it.
