Hand animation plays higher than before

Hand animation plays too high, it feels like the classic version of Minecraft (my FOV is 80).

Steps to reproduce:

1. Enter a world in 24w34a (it will be better if you can record a video)
2. Repeatedly place blocks
3. Do it again in 1.21.1
4. Compare the videos in a video editing software by slowing them down, see whether the animation's highest point is higher than 1.21.1's

Observed result:
The animation's highest point is higher than in 1.21.1.

Expected result:
The animation is the same as in 1.21.1.
