I'm pretty sure the following patch fixes it, but would you please do the usual with it anyway. As this changes a Lisp macro, the entire CC Mode needs to be rebuilt after patching. Thanks!

With these buffer contents:

... "x" an= d "y" are highlighted as types [EDIT: keywords],
and "z&q= uot; is not.

... "x" an= d "y" are highlighted as types [EDIT: keywords],
