Can confirm that this still happens in Minecraft 1.12, on Mac OS Sierra, with Java 8 runtime. A detailed description of how this happens is I will enter a rabbit pen(enclosed securely with fences) with dandelions to breed them. When I still have dandelions in hand they are fine; but when I run out of dandelions after feeding the rabbits, they panic and some rabbits(both adult and baby rabbits can) near the edge of fences will leap right over the fence, and interestingly, will be seen/heard getting hurt(the red animation and sound) upon hitting the surrounding walls(they jump right at the walls) outside the fence
