Launching an ender pearl into an end gateway now results in taking damage

With the advent of the 1.9 update, end gateways were introduced to the end, allowing players to throw ender pearls into them without taking damage, unlike conventional ender pearl teleportation. However, in version 1.21 Pre-Release 1, this behavior has been altered, and now throwing ender pearls into end gateways results in taking damage. This modification could be linked to the addition of teleportation sounds.

Steps to reproduce

1. Travel to the End
2. Kill the ender dragon
3. In survival mode, toss an ender pearl into the end gateway

Observed outcome: Damage is taken.
Expected outcome: No damage should occur, consistent with previous versions.
