When converting, only the body of the Piglin shakes. In JE both the head and body shake.
Steps to repro:
On BE spawn a piglin in the overworld, note only the body shakes
In JE do the same and note the head shakes to making the animation more noticeable
What I expected:
For the animations to be the same.
Original description:
I spawned in some piglin in the overworld to test their zombified mechanic and found that they did become zombified but didn't shake beforehand.
Cannot reproduce on 1.16.0.63. While it may not look like they're shaking, when they stand still you can see that they are indeed shaking.
