assuming the SJK is an HV diode and 2x 4148 in the pic, then probably
much the same circuit

Right, now I'm back in the lab, turns out this really is just a bypass cap, it's connected directly accross the main HT cap. I had at first assumed it was connected to the current sense circuit or thereabouts.

No bypass caps on any of the other circuits using this controller though, I guess a high voltage 0.1uF will do. (not SMD this time)

Thanks for the schematic links,

Gareth.

I wonder if it was a multi-layer cap in there with metal migration
growth leading to short.
Any other similar caps on there?
