I don't think it's a ferroresonant transformer.  I think the cap is only for
PFC. If you do the calculations (which might even be on my PFC page), you
can see that 10 uF at 600V transforms (turns ratio squared) to 250 uF at
120V, or about 11 ohms reactance... fairly close to the inductive leakage
reactance.
