Inadequate capacitive bypassing

Not that capacitance directly in parallel with a zener has limited effectiveness to begin with, but yeah - RC filtering downstream is to be desired.

yep, the capacitance with the Zener impedance would be the first RC time constant, but better add some more R before the C.
