Experience orbs will rapidly accelerate towards the ground, if they were being pulled towards the player but the orbs (or the player) moved out of attraction range.

Reproduction Steps

• Build a dispenser throwing bottles o' enchanting against a wall
• Move up close enough to the experience orbs to where you'll start slightly pulling them towards but not close enough to absorb them
• Observe the behaviour of the XP orbs

Observed Results

• XP orbs behave normally if there's no player pulling on them
• If a player pulled on the XP orbs, they will rapidly zoom towards the floor even after they moved away from the player/player moved away.
