Axolotls on a lead still act as though they're swimming when pulled out of water

So I was spawning in some Axolotls to play with their new 21w13a functionality when I got the rare axolotl for the very first time. I had to get it into its own little enclosure. So I attached a lead to it, and flew to another part of the world. In doing so, the axolotl took a dip in a river before I pulled it out of the river.

That is when it went haywire. It was acting like it was still in the water. It was swimming around in the air very fast, as if it was swimming in water. I couldn't get it to stop. It was even swimming through the air, like it was flying.
