Changing an Arrow's Motion using /data causes client-server-desync

When you update the Motion of a flying Arrow with /data, it does only update serverside.

To reproduce, you can use the following commands:

/summon arrow ~ ~2 ~ {NoGravity:1b}

/data merge entity @e[type=arrow,limit=1,sort=nearest] {Motion:[0d,0d,-0.5d]}

You should see, that the arrow ow "jumps" every so often to its new sever-side position but still facing the direction it was facing when it was summoned.
