[MC-108605] Attached blocks on End platform sometimes drop

The bug

Attached blocks on end platform sometimes drop and appear on the ground when re-entering the end.

How to reproduce

Go into the End
Place a block on the starting obsidian platform, so that it's in the area that gets reset every time you enter the End
Place a torch, a button, a sign or something else that can just be attached to other blocks on that block so that it is also in the reset area. To be sure, place one on all sides of the block, sometimes it doesn't drop.
Leave the End.
Go into the End again.
→ Torches (etc.) that were attached on certain sides drop instead of getting deleted.

One year with no comments?

Issue seems to be fixed for 1.13.1.

~~Unable to reproduce for 1.13.1 too.~~

Nope, still happens. I just tried it with redstone dust, redstone torches (apparently only drop in two of the four directions), signs (might not drop on the side, my test isn't very clear, but definitely drop when on top), ladders (only two sides) and item frames (including content).

Can confirm that this is still an issue in 21w05b.
