[MC-159349] Bottom half of door is missing when an entity is passing through while placing it

The bug

When a door is placed while an entity, such as a bee or a chicken, is passing through the same block, the door is created missing its bottom half. The door will completely vanish when the chunk is reloaded. This means that the server doesn't properly inform the client that the door could not be placed successfully.

To reproduce

Put a flower (or seeds) in your offhand
Summon a bee (or a chicken)
Put a door in your main hand
Place a door on the ground at the same moment the bee (or the chicken) enters the block
→ ❌ The bottom half of the door is missing

The same thing happens for chickens as well; pretty sure that's not a new issue.

The door is actually not placed, but the client doesn't realize that. When relogging, the half door disappears again.

oh, that's correct.

with bees the bug appears easier to recreate and come across though, making it more critical.

I updated the ticket to reflect that this does not only happen for bees. I was unable to find another ticket about this, so I'm assuming it's not been reported already.
