The Bug:

Ender pearls sometimes teleport entities one block too high.

I was testing if MC-276716 was properly fixed and discovered that ender pearls occasionally teleport you one block too high.

Steps to Reproduce:

1. Obtain some ender pearls.
2. Look directly down and constantly throw ender pearls.

Observed Behavior:

Ender pearls sometimes teleport entities one block too high.

Expected Behavior:

Ender pearls would not teleport entities one block too high.
