Falling sand summons without animation

When using following command:

/summon FallingSand ~ ~1 ~

{TileID:1,Motion:[0.0,1.5,-0.1],Time:1}

It doesn't shows the "flight" or "falling"-animation anymore. The block just appears on ground after a short while (I guess the flight/falling is just invisible).

It works perfectly with 14w06b - but it's broken since 14w07a
