If the "enderPearlsVanishOnDeath" gamerule is enabled, Ender pearls disappear upon the death of their owner. However, this rule only affects player-owned Ender pearls and does not apply to those owned by non-player entities. Relates to MC-269615 and MC-269617.

Steps to reproduce

1. Construct a bubble column enabling endless bouncing for Ender pearls
2. Ensure that the gamerule "enderPearlsVanishOnDeath" is set to true
3. Spawn a panda

4. /execute as @e[type=minecraft:ender_pearl] at @s run data modify entity @s Owner set from entity @e[type=minecraft:panda,limit=1] UUID

5. Kill the panda

Observed: The Ender pearl remains present without an owner. Upon allowing the Ender pearl to collide with a block, no entity gets teleported.
Expected: The Ender pearl should disappear since the panda has died.
