Please take a look at the example I have given in my very first post.
There you see that font-lock is handling top-level lisp code incorrectly.
This is definitely a bug.

I don't agree with  you that customizing a variable is the recommended
way to fix a bug. But if there's really no other way to handle it, then it
should be documented at least.
