Fixed for 1.9
this continues in 1.8 release
my skin and it's image
Also on 1.8
The iron one as well, it still existing in 14w28b, so thev problem was only fixed in wooden ones.
and in 14w28b as well, but the hitbox is fixed, although the image of the trapdoor is wrong
Thay have jump boost kinda effect on them, so, they never take damage, it's not a bug. :I
I gave two tamed rabbits a carrot, they didn't breed though, I also cannot see any difference between a untamed or a tamed one, as they act the same, don't teleport and don't breed(this is actually a bug report, not talking about the appearence of the rabbits)
I had it in a snapshot
It is still an issue in 1.9.2
