Entities which throw an enderpearl at another entity will be placed further away than expected, leaving a gap between the two.

Steps to Reproduce:

1. Place down an armor stand
2. Stand ~10 blocks away from it
3. Throw an enderpearl, hitting the armor stand

Observed Behavior:

The player will be placed ~1 block away from the armor stand.

Expected Result:

The player would be placed directly next to the armor stand because that is where the enderpearl landed/collided.

Original description:
When you use an ender pearl to an entity, you aren't fully next to it. You can test this by placing an armor stand, pressing F3+B to turn on hitboxes, and when you throw an ender pearl to it you'll notice you're standing pretty far from them; even the hitboxes are not close. If the ender pearl hits the eye level, however, you're close to it.
