Incorrect item drop animation when increasing tick speed using tick rate

Item drops fly with incorrect animation when using tick rate.

What I expected to happen was...:
Normal item dropping animation when increasing tick speed using tick rate, just sped up.

What actually happened was...:
Dropped item goes with normal speed at first and then quickly teleports to the ground.

Steps to Reproduce:
1. Increase tick speed using tick rate to more than 20 (30 - 50 are the most visible).
2. Drop any item
