Flying Traders

So, I went on my MCPE realm, hopped into creative mode, found a Wandering Trader near spawn. It wasn’t moving, I hadn’t even realized they were out of Beta. I then proceeded to punch the Trader, and the next thing I know, the Trader is floating up and up, like it was hit by a shulker bullet. I spawned in another to see if it would happen again, and it did. I then left a screenshot of this on my realm club.
