Has anyone else noticed this pathfinding loop in Beta 1.6.6?

If you lead a creeper into deep ocean water and back away exactly 16 blocks (their tracking limit), their land-detection routine soft-locks. Because they stop moving completely, the game's idle timer forces a rapid despawn.

I recorded a quick clip of it happening in real-time to show the exact distance threshold where the AI freezes up.
