Possible bug: Knock Off does not remove held item if the target faints

[baldr 32]

I'm not sure if this is a bug or intended behavior (could not found any source how it's supposed to work). The thing is that Knock Off does not remove the held item of the target if the target faints as a result of the move. I assumed it should always remove the item (except for Sticky Hold, Arceus, mega stones etc.)? Or is fainting actually supposed to prevent the effect?

Thank you for reporting. Fainted pokemon should still get their item knocked off
