Physics bug with animals on leash bouncing on slime blocks

The bug

If you put animals, a cow for example, on a lead, and tie them high enough that they barely are able to touch the floor, and put slime blocks under them, they can sometimes jump very high.

It's because when they're on a Lead, lifted above the ground, they gain velocity(speed). Therefore, when they hit the Slime blocks, they bounce higher, as they have a higher rate of speed when falling. Similarly, if they hit the ground, they take fall damage (no matter how high above the ground they were).

If you fly while dragging them around on a leash every downward motion gets added to their "total distance fallen" counter, but the upward motions don't get subtracted. Let them yo-yo for long enough and any landing other than a water landing is fatal. I've been doing stuff like that when raising cattle for leather. Execute 5 of them at a time by flying them around for awhile then landing, or just go up 50 blocks and turn flying off.
So yeah, my point is that you need to experiment with giving them a huge fall distance build up then drop them on a slime block. For science!

Tokes: Ah I see, how did I not think of that?
Thought, I noticed that slime blocks have limit on how far they can bounce you; I tried on 2000 blocks, and 200 and gave me same result: ~ 100 blocks. Pretty unfortunate, isn't it? =)

Same cause as MC-14167, except they bounce on slime blocks rather than die horribly.

Is this still a concern in the current Snapshot 14w08a or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
