Polar bear movement is way too sensitive in water

The Bug

When a polar bear is swimming, sometimes it cannot pathfind correctly. This also causes polar bears to take a ridiculous amount of knockback while swimming in water. To reproduce, try fighting a polar bear in water, and notice the constant spinning and the extreme knockback the polar bear receives when you hit it (even more so when using the knockback enchant).

Steps to Reproduce

• Summon a polar bear in a large area of water.
• Attack the polar bear with a sprint attack by punching it and as you do this, take note of how many blocks it travels.

Observed Behavior

The movement of polar bears whilst they're in water is too sensitive.

Expected Behavior

The movement of polar bears whilst they're in water would not be too sensitive.
