Squid and glow squid collision error and rubberbanding

Squid and glow squid collision rule error.
Also affects the bubble columns.
16w06a: No rubberbanding, but still collision error or not synchronized.
In 16w07a rubberbanding again.
In the water also slightly affect.

Code analysis

Based on 1.11 decompiled using MCP 9.35 rc1

The problem is that the motion handling part of the code is only done server-side. This includes setting the horizontal motion (X and Z) to 0 and reducing the vertical motion (Y) when the squid is not in water. Because of that the server resets the horizontal constantly while client-side it changes when the player pushes the squid.

Like @unknown says squids are desynchronized. You can push them around but once you hit them, they will reappear at their original position.

I tested this in 18w22c and got the exact same result.

I can't believe this bug hasn't been fixed yet and has been around for so long, even if Glow Squid is about to be released.

It's still there in 24w18a but a bit more difficult to see. A higher than normal tickrate makes it easy to reproduce:
