### Godot version

v4.1.rc1.official [1f9e540f1]

### System information

Godot v4.1.rc1 - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 960 (NVIDIA; 31.0.15.3623) - AMD FX(tm)-6300 Six-Core Processor (6 Threads)

### Issue description

When damping is used and a particle is fully stopped, it gets new shape, color, angular velocity, etc. It looks like it's being recreated from scratch.

### Steps to reproduce

1. Run the project.
2. Open block_hit_particles.tscn.
