Does making a Pokémon faint in the Battle Frontier and the later battle facilities still reduce its friendship value?

Question

If when a Pokémon faints, it loses friendship values. But I wonder if this principle applies to the battle facilities (ie Battle Frontier, Battle Chateau, etc) because I’ve lost count of how many times my Pokemon have fainted there.

Comments

I don't think they modify the Pokemon at all (besides occasionally giving them a ribbon), so I think the answer is no. However, I have not paid attention to any of my Pokemon's friendship while using them in a battle frontier.
