End exit portal changing state duplicates torches on +x and +z

The bug
When the End Exit Portal changes state (open/close), the torches in the structure on the +X and +Z direction drops as items and don't get destroyed as a block. This causes torch duplication. Torches on the -X and -Z direction are not affected.

Likely an artifact from MC-272790. Possibly a bug in block placement order.

Steps to reproduce

1. Go to the End dimension and go to the Exit Portal
2. (optional) /tick freeze to see the bug better
3. Kill the Ender Dragon (eg. /kill @e[type=ender_dragon]) / Resummon the Ender Dragon by placing End Crystals
4. Observe that two torch items, namely in the +X and +Z direction, are generated, while none of the torch blocks are destroyed
