animation glitch when block bounces on slime block

When a block entity, (EX: anvil, sand, gravel, dragon egg), bounces on a slime block, Minecraft fails to display the animation correctly. It appears as if the block stops bouncing to soon.

To recreate:
1.Place a slime block on the ground.
2.Drop an anvil/sand block on it.

I attached a video of this, but had to make it very short to fit in 10 MB.
