Hi there, thanks for writing in.
It sounds like your concern is the leaking antifreeze with the ignition on, engine off. Leaking coolant is never a normal condition on any car, even if it's remotely modern. Anytime there is leaking antifreeze, the leak needs to be addressed. Even if the car wasn't overheating, or has never even come close to overheating, you should have the leak checked. Your engine relies on the coolant/antifreeze to prevent it from overheating, which can cause serious engine damage. I would recommend having a qualified professional, such as one from YourMechanic, diagnose the source of the coolant leak. Good luck.
