Pigs don't float when ridden in water

Since 25w44a, when horses or other mounts are ridden in water, they float on the surface instead of sinking and causing the player to dismount. This however doesn’t apply to pigs - a pig sinks if ridden in water, and the player eventually dismounts. While not explicitly mentioned in the changelog, pigs are a mob the player can mount and travel on in the Overworld, so it would be expected that it behaves similarly to other mounts when it comes to traveling over water.

How to reproduce

• Find or build a body of water that is at least 2 blocks deep

• Spawn a pig

• Place a saddle on the pig

• Hold a carrot on a stick (so it can move to an area with deep enough water)

• Mount the pig

• When moving in an area with water that is 2 blocks deep, the pig sinks and the player is eventually dismounted
