### Godot version

Godot 4 stable and Godot 3.x LTS

### System information

Fedora linux

### Issue description

If you use some custom logic inside _integrate_forces() to alter the state linear velocity and there is any reference to linear_velocity in physics process, the result in godot 3.5 is that it moves just a little bit, while in godot 4 is totally still.

### Steps to reproduce

For the example i created a simple scene in which i apply a force on the linear velocity in  _integrate_forces()  and added a line that add zero to it in physics process. You will not see any move, but it will work fine if you comment the line adding zero.
