When I was playing my hardcore world, I came across a village somewhere in a snowy tundra, I realized that there was a polar bear and it didn't seem to jump over 1 block. I even made it come after me to see if it was just a one time thing but, he doesn't seem to budge. I've tried this with leads, and I've tried it with another world and it still didn't seem to work. I don't know if this just is happening to me, and I know it's a minor detail but. It's hard to transport polar bears and I need some for my build >.<, anyways have a good day! if you need any more contact from me please let me know!
