Glad you asked to look at it again, I put my glasses on this time, that cap is wired in parallel to the 5k resistor; also there are no snubbers on the board. I have added to my schematic below. Doesnt seem logical to place a cap of that size there, unless they intend to delay the switching of the lower bridge relative to the upper, but it will be loading down the booster circuit with extra capacitance.
