Parity Issue: Frogs bob at the surface of the water constantly moving, different from how they swim in Bedrock

The bug

Frogs swim differently in Java edition than they do in Bedrock. In Java edition, frogs swim at the surface of the water, constantly bobbing up and down, and they almost never stop moving, if at all.

Contrast this with Bedrock edition, where frogs swim under the water not clumsily bobbing, and occasionally pause for a while.

How to reproduce

1. Spawn a frog in Java edition, far from land. Observe how it bobs up and down above the surface of the water and doesn't stop swimming.

2. Do the same in bedrock. They will swim under the surface and occasionally pause.

The videos below demonstrate these differences in how frogs swim between the two versions
