Player head animation is different

Since 1.2.0 (Better Together Update), player head uses different animations in 3rd person camera, as the head will instantly snap to camera rotation (the animation used on alpha\beta version of Java Edition), while on 1.1.5 and below, player head has a slightly delay (or lag behind) before finally matching camera rotation

Steps to reproduce:

1. Go to 3rd person back/front
2. Move your camera around

Expected results:
Player head has a slightly delay (or lag behind) before finally matching the camera rotation, just like in Bedrock 1.1.5.

Observed results:
Player Head instantly snap to camera rotation.
