Foxes getting stuck in fences/fence gates

Foxes will repeatedly get stuck in fences and fence gates either laid out straight or in corners and cannot move. Repeatable issue by placing foxes in an open fenced in area and waiting. Usually between 5-10 out of about 40 will get stuck in a 20x20 area. Foxes will also glitch through fencegates when chasing chickens, or are able to jump over them with no blocks nearby.
