Summary 0005894: Rollers sometimes keep working even when powered off

Description I built a long west->east roller along a track that led straight to a series of upward ramps (which were too steep), and after a short while the cart would start rapidly swapping between the ramp tile and the roller tile. Even after I turned off the rollers, the cart would continue bouncing back and forth as if it were being powered.

If I send a dwarf to walk over the oscillating cart, it quickly gets beaten to death; upon deconstructing the rollers, the cart finally stops moving and can be safely collected.

If nothing else, maybe rollers placed directly on a ramp should push the cart up with constant minimum speed, so that at least it does go up.
