It comes from a change hidden in a commit with an innocuous message, 
4deb5bd9b1d400b9f932053eb6900e5700414ce8. The change is:

-  (setq-local font-lock-defaults (list js--font-lock-keywords))
+  (setq-local font-lock-defaults '(js--font-lock-keywords))

I don't see a better fix for this except by reverting it (or using a 
quasiquote). Stefan?
