LT8364 / LT3094 VIOC behaviour

I am attempting to use the VIOC capability of the LT3094 to control an upstream LT8364, as shown:

This works as expected with little to no bypass capacitor on the LT3094 SET pin:

However, increasing the bypass cap (C7) to 100nF or more prevents the devices from properly starting:

Is there an error in my design / simulation, or is this a bug in either the LT3094 or LT8364?
