@LateLag Firstly, I did not say that PS4 was Bedrock, I was saying that the issue is also affecting PS4 alongside Bedrock. And secondly, If you view the attached gif, it clearly shows the leg using the exact same animation as the arms, even down to the slight pausing when it gets to it's default postion. And if it were to be intentional, then why isn't the other leg using the same animation?
I would imagine that each arm would be animated individually since both arms don't wave when left clicking for example, and judging by the gif, the arms do only go back and forth and don't rotate slightly like in java.
