According to jolt dev on godot github (and summed up):
- The velocity halt is to be expected due to how the jolt physics engine does its calculations, which follow a simplified version of real life physics.
- However, this can be “worked around” by dynamically setting the friction. The key here is to have no friction the first landing frame.
