The Bug

When endermen freeze in powdered snow, suffocate, take damage from rain/water, etc. when they are riding an entity (such as a boat), they attempt to teleport, resulting in teleportation particles and sounds of the Enderman teleporting without any teleportation occurring.

Steps to Reproduce

1. Summon a boat with an enderman in it:

   /summon oak_boat ~ ~ ~ {Passengers:[{id:enderman}]}

2. Set the weather to rain:

   /weather rain

3. Look at the enderman closely, and note if it attempts to teleport while taking damage in the rain.

Observed Results

The enderman attempts to teleport out of the boat but fails continuously, resulting in an abnormally large amount of teleportation particles and sounds.

Expected Results

Endermen take damage in the boat but do not attempt to teleport.
