Sitting leashed cats slide across the ground when pulled, despite being in sitting pose.

When a cat or dog is commanded to sit and then leashed, it will still move when the player walks away while holding the lead. The cat/dog remains in the sitting pose but slides across the ground instead of walking or staying still. This behavior looks visually strange and unrealistic, as sitting mobs are expected to either stay put or stand before moving.

Observed Result:

The sitting cat/dog slides across the ground while maintaining its sitting posture, which looks unnatural and goofy.

Expected Result:

The cat/dog should first stand up before moving. It should follow the player on the leash only after standing or stay in place until the player ties it to a fence or unleashes it. Sitting cats should not move while remaining in a sitting pose.
