Dragon's Grip going on cooldown after breaking a door!?

Canas

I was playing Ghostface on Yamaoka Estate with the perks Brutal Strength and Dragon's Grip equipped. I noticed how the 2nd perk went on cooldown right after I broke a door within the mainbuilding.

I'm quite sure that this has to be a bug - the perk description only mentions interactions with generators and not with other objects on the map. I'm playing on pc/Steam, by the way.
