Here is evidence of him running away from the player
The sandstone particles at his feet shows he is running away and not tamed
It isn't taming it. You can only tame it if you are sitting still while holding a carrot and the rabbit comes towards you. if you go up to the rabbit and right click it while holding a carrot then he will give off hearts but he isn't tamed because he still runs away from you. The bug is that the rabbit is giving off hearts even though he isn't tamed or being tamed.
The Rabbits are not breeding because they are not tamed. You tame them the same way you do ocelots: standing still and holding a carrot. Once the rabbit is close enough you feed it to him and you will see these gray particles emit with the heart particles. The same particles you see when taming a wolf. Once tamed you can make the two rabbits breed.
Bedrock version 1.19.51, bug is still in effect. PLEASE FIX ALREADY.
