User forces are not auto cleared after physics step

[newDINO]

Documents say that forces are automatically cleared each physics step, but there doesn't seem to be code doing it. For example, I checked the references of reset_forces() using vscode rust-analyzer, and there is no usage within rapier code base. I also checked the reference of Rigidbody.forces and RigidbodyForces.user_force and there doesn't seem to be any place where they are cleared except reset_forces.

I wonder if this is an error of the documents or the code.

To state that this issue is not made up. I created a simple example at newDINO/rapier@da6a9a1.
Run cargo run --bin all_examples3 and select the "(Debug) user force" example. User force is only added during initialization. If user forces are auto cleared, the cube should come to rest rather than keep accelerating.
