Modifying a falling block entity's velocity server side causes bouncing of the entity's on the client, as the client assumes the block is falling, even when it isn't.

If I were to take a falling block entity and alter its velocity to 0 on a minecraft server, the client would see it rubber banding as it assumes it falls, and then is told that it's position is not where it thinks it went. Resulting in a situation where the client sees a falling block falling circa 2-3 blocks then rubber banding back to its original location. Now this isn't really a bug, as without any modifications to client or server it works as intended, but this is a roadblock in server side modifications as it close's doors to cool things that could be done with controllable block entities.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
