Dragons in Advanced Dragons 2 don't get teleported

Affects currently Live Content: Yes

Verification Builds: all versions since 1.18.0.02 

Impact: Major function in Advanced Dragons 2 does not work. We are getting a lot of negative feedback regarding this issue. It seems all devices are impacted.

Repro Steps:

1. Open Advanced Dragons 2, and skip the tutorial.
2. Teleport to 1242 91 -457 and unlock the teleport.
3. Teleport to the Main Hall, and spawn, grow and tame a dragon using rotten flesh.
4. Teleport back to the Dungeon.

Observed Results: When teleporting to a far away point the dragon's geometry is not displayed, or is standing in one position. The dragon is still following the player and attacking mobs, but not visibly. It works again when reloading the map.

Expected Results: The dragon is fully displayed.

Screenshots/Videos attached: Yes   Video Link: https://youtu.be/QVCxwuDcvxg

Notes: The dragon is supposed to follow its owner, even when teleporting far away. The dragon uses minecraft:behavior.follow_owner and minecraft:tick_world with a radius of 1, so that the chunk the dragon is in when the player teleports is still loaded.
