Shooting an arrow at an updating repeater will cause the arrow to "Flinch" multiple times until the repeater stops changing states.

What I expected to happen was the arrow would be unaffected by the updating repeater.

What actually happened was that the arrow would move every time the repeater updated.

Steps To Reproduce:
1. Create a clock or something that can send power to a repeater.
2. Shoot an arrow at the top of a repeater.
3. Power or un-power the repeater.
