Dogs don't attack each other anymore

I noticed that when I tame a wolf, cat, or parrot right after hitting it, my other dogs wouldn't attack it. I like causing dogs to attack other pets for fun. I tested this in another world and it worked. In the video in the first clip in that other world, I demonstrated the bug in 20W51A because in the clip that would be what would've happened IF I demonstrated it in 20W49A. It's always that one world that I'm having problems with, the same world that is affected by MC-201217.
