On some language modes, most noticeable Clojure mode, the keywords are
known as builtins and converted to gr-syntax-name instead of
gr-syntax-keyword. Given that gr-syntax-name is not styled, the
impression is that the highlighting process doesn't work, even though it
does. Style gr-syntax-name in the same way as gr-syntax-keyword.
