Why are there confirmation boxes in dungeon?

[Klamor]

My guess would be that you don't accidentally click it, because in some instances, you are attacked immediately by whatever is behind the door / gate / etc. (I think)

I can only think of a single instance of this, and that's in Haukke Manor (normal mode) when opening the door to the cell that has the Yellow Key in it. However, if you're off to the side enough, you're out of line-of-sight from the enemies and they don't agro you when you open the door. That means it's not a trigger from opening the door, but simply being within their sight radius.

Other than that, I can't think of any other case where an attack is triggered from activating an object in a dungeon. Please correct me if I'm wrong.
