Rapid trapdoor movement with items on top of it causes ghost items

Using a really fast clock that controls a trapdoor (any type) with items on top causes items to be falling below the trapdoor but they are ghost items. cant be interacted, likely  a client side error / view. And when the items take at least 5-10 seconds of air travel, they glitch back onto the trapdoor, and it loops going down and up.
