ALL 12 Volt supplied accessories will be pulling power from the 12 volt battery / inverter, which power is then replenished with power draw from the HV traction battery.
The demand required for heating the front seats is on the lower end of the scale really.
The HRW is a larger drain than the heated seat, given the size of the element bonded to the glass.
I am willing to bet, IF it was possible to turn on the heated seats for 30 minutes in standby mode and measured the drain from the 12 volt battery, it would be fairly small.
But in comparison, try running your headlights for one hour in standby mode and I am more than certain your 12 volt battery would be completely flat.
You get nothing for nothing, in this life !.
The cabin heater has a split / twin power sauce in order to make it operate.
Cabin blower motor operates from the 12 volt circuit, but the HV orange cables are there to provide energy for the PTC heater element.
A perfect partnership, as one is no good, with out the other ! ?.
