Entering an end gateway does not consistently grant the Remote Getaway advancement

The Remote Getaway advancement is not always granted when using an end gateway. This occurs both when using ender pearls and when simply moving into it.
This is not a regression of MC-270749 since there is no consistent way (from what I can tell) to get the bug to occur.

To reproduce

1. /advancement revoke @s only minecraft:end/enter_end_gateway
   

2. Throw an ender pearl through a naturally generated gateway
3. Repeat steps 1-2 until the advancement is not granted

The following demonstrates the bug with the first gateway to naturally generate on seed -1768633086023783819.
