This happens because face-new-frame-defaults has `unspecified' for all
the attributes of `italic' face (and all other faces as well).  Try

  (face-all-attributes 'italic (selected-frame))

and you will get what you expect.

I don't know, but it sounds like the doc string is at least misleading
in this regard.  OTOH, this function is not used anywhere in Emacs, so
it could be buggy.

What is your use-case, exactly?
