Motion:[X,Y,Z] tag not affecting Fireballs, SmallFireballs, or WitherSkulls

When attempting to spawn in a Fireball, SmallFireball, or WitherSkull and giving it velocity with the Motion:[X,Y,Z] tag, both types of fireballs immediately despawn, not showing any signs of movement prior to despawning, and WitherSkulls do not despawn, but additionally have no velocity and will simply hover in mid-air, not moving. This has been tested with all three of the above projectiles that will respond to the direction:[X,Y,Z] tag.

Fireballs and other entities that are not falling sand use the {direction:[X,Y,Z]} Feature, Blocks use motion. Direction is working fine for me though in 13w38c. Falling sand is not effected though, which is a bug.

works as intended.

just adding this here so people see it.
the direction [x,y,z] is case sensitive. spelling it "Direction[x,y,z}" will not work (at least in the cases I've tested).

Ok, so just to help you out, i did some tests wih MCedit with the following code:

/summon SmallFireball ~ ~10 ~ {direction:[0.0,-1.0,0.0]}

Executing this will cause the projectile to appear for a single tick. After that, the entity still exists, although invisible. As soon as it hits a mob/block, it will still cause fire. The motion given works, and it will move downward. Only problem is that it's not actually visible. Fiddling around with some tags didnt seem to help, so I would say it is a visual bug.

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. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been deliviered.

Fireballs, SmallFireballs and WitherSkulls should not be affected by motion because the direction tag says them where to fly. (This is probably also one of the reasons why Fireballs aren't affected by gravity).

Is this still an issue in 1.9 or 1.9.1-pre3?

Major necrobump but this seems to have been fixed (probably in whatever version removed the direction tag from these entities).
