MC-201857A desync occurs when leads are attached to entities that are just barely out of reach
The Bug:
A desync occurs when leads are attached to entities that are just barely out of reach.
Client-side, it appears like a lead is attached to the said entity and will not break no matter how far away you go.
Steps to Reproduce:
- Enter creative mode and obtain a lead.
- Summon a boat and attach a lead to it.
- Fly upwards in the air and as the boat travels downward, quickly detach and reattach the lead to it.
Observed Behavior:
A desync occurs resulting in the lead attaching to the entity client-side, but not server-side.
Expected Behavior:
No desync occurs.

I cannot properly describe this issue, but here's how to reproduce it :
When a mob has the levitation effect, if one has a lead attached to it, the mob can sometimes "ignore" the lead and continue flying upwards, while the lead is still, visibly, attached to the mob. In that case, the lead disappears at some angles of the camera. Here's how to reproduce it :
