Axolotl movement glitch on stairs

Related issues : MC-208586 MC-208589

I made a small pool for some Axolotls and used some stair blocks in it. When the Axolotl swam up onto the solid block island I made and attempted to return to the water, MC-208589 came into play, and it "fell into" the stair blocks at the edge, getting stuck spinning at a vertical angle as seen in the pictures. It could not escape this situation and died as a result from lack of water.

The path finding and on-land animations, as stated in the reports posted and others, definitely seems to be the problem.
