However, there is a spell that does have the "fear" descriptor that doesn't include the "mind-affecting" descriptor: Haunting Mists. It would seem that even the effects of the spell (ability damage vs drain for a non-physical ability) would affect undead and was written, possibly, with that in mind.
Just because the Bestiary lists fear attacks and frightful presence as mind-affecting doesn't mean that ALL fear is mind-affecting.
One, why would that gem be buried so deeply in the text and only be included on those two entries with language specific to those two entries?
Two, those descriptions describe a subset of fear. Mind-affecting is a modifier of those particular fear attacks in both of those instances (The authors did not write, "Fear is always mind-affecting".
Three, fear and mind-affecting would be surplusage; they would be duplicative and therefore why include both where one would suffice unless they meant different things?
Since undead immunity does not list fear as one of the proscribed descriptors and the shaken condition is an untyped penalty and therefore not a morale effect; I would argue that demoralizing via intimidate should be a viable option vs undead. (Which relates back to the original discussion RE a Dazzling Display build.)
