Treat standalone default/initial/inherit in font-family as invalid

Treat standalone default/initial/inherit in font-family as invalid

Treat standalone default/initial/inherit in font-family as invalid in
the case where it is not a substring of a family name and it is at the
end of the current family name (next token is comma or end of
value list).

Test is adapted according to this new behavior.

Behavior matches FireFox.
