Beacon's power reverts back to previous one on world reload

The beacon's power will back to the previous one (or not selected) after reloading the game if its pyramid was set on chunk borders. The change of power cannot appeared.

Reproduce:

I made a video that we can know it clearer and easier to reproduce this issue. Its size was too large, so I post it on https://www.bilibili.com/video/BV1kq4y1D7T6 .

1. Put 9 available golden blocks (or iron blocks, diamond blocks, netherite blocks, emerald blocks) on the chunk border, then put a beacon.
2. Select power Speed.
3. Reload the game, select power Haste.
4. Reload the game again, the power is still Speed.

Also you can see that the subscribe shows "Beacon activates" after reloading the game. ← This is probably another issue, but I just put it here.

I created a new world, there're still problems.
