AnimationPlayer Stop does not automatically reset section

### Tested versions

I use Godot 4.4.1

### System information

Win10 Godot4.4.1

### Issue description

1. Call AnimationPlayer.PlaySectionWithMarkers()
2. Call AnimationPlayer.Stop()
3. Call AnimationPlayer.Play()
4. Then the animtion will still start from the previous section

### Steps to reproduce

1. Call AnimationPlayer.PlaySectionWithMarkers()
2. Call AnimationPlayer.Stop()
3. Call AnimationPlayer.Play()
4. Then the animtion will still start from the previous section

### Minimal reproduction project (MRP)

.

Start by reproducing the issue in Godot 4.4.1 using AnimationPlayer.PlaySectionWithMarkers(), AnimationPlayer.Stop(), and AnimationPlayer.Play(). Trace the AnimationPlayer playback state involved in section playback; done means Play() after Stop() starts the animation from the expected initial position rather than the previous section.
