Sand duping not working on Folia 1.21

[QGavoille]

Expected behavior

With Paper config unsupported-settings/allow-unsafe-end-portal-teleportation set to true, the gravity blocks duplication via end portal is supposed to work.

Observed/Actual behavior

No blocks are appearing on the end side when the machine is running, the overworld behavior seems correct.

Steps/models to reproduce

Build a duper (i used a 10gt for the tests but it should be the same with all types of dupers)
Run it and put a second account on the end side

Plugin and Datapack List

None

Folia version

Folia version 1.21.1-DEV-dev/1.21.1@06d719d (2024-10-30T16:02:28Z) (Implementing API version 1.21.1-R0.1-SNAPSHOT)

Other

I tested the same thing on the latest paper version (paper 1.21.1 build 128) and the dupe worked with the exact same configuration.

this is correct, when I moved from master 9a19e42 to dev/1.21.1 06d719d the duping does not work.
Not sure which commit caused this problem
