Levitation Launches Player If Damaged

When using levitation on a player, if the player takes damage it causes the player to be launches high in the air. This affect is commonly seen when using levitation effects to grant slow fall or no fall. Most common in levitation over 200. This makes it extremely hard to use levitation in custom maps as there is no way to prevent this affect. This is probably due to an issue with knockback and levitation interacting peculiarly.
