That's because on GUI frames there's no real default for these
attributes (unlike on a TTY where we inherit the colors of the
terminal). So we simply _cannot_ reset the attributes like that,
because there's nothing to reset to. E.g., unspecified-fg only has
meaning on a TTY frame.

Doesn't customizing a face record the original value in some property
of the face symbol? If so, reverting the customizations should use
those recorded values, I think.
