Fox head and body rotate simultaneously while sitting

Description:

When an adult fox is sitting, its head rotates together with its body instead of moving independently before the body follows. This differs from the behaviour in Java Edition, where the head moves independently of the body.

Steps to Reproduce:

1. Spawn an adult fox.

2. Wait for the fox to enter its sitting position.

3. Wait for the fox to look somewhere.

4. Observe how the fox's head and body rotate.

Expected Result:
The fox's head should rotate independently to look towards the target location before its body turns to follow, as it does in Java Edition.

Actual Result:
The fox's head and body rotate simultaneously, causing the entire body to turn at the same time as the head.
