staticbody2d constant linear velocity not affecting colliding bodies

[alexspoon]

Describe the bug

i'm trying to make a conveyor belt but the constant linear velocity property of the staticbody2d is not being applied to colliding rigidbody2ds. i set the constant velocity in a script according to a direction and speed, and i print the constant linear velocity value in the console to show that the value is set, just not working as expected.

To Reproduce

Steps to reproduce the behavior:

1. run game
2. watch box fall on conveyor belt and not move
3. try to drop other boxes on conveyor and they do not move either
4. read console and see that the constant linear velocity value is set

Expected behavior

i expected the box to slowly be pushed along the conveyor belt, like how the property is described to work.

Environment:

• OS: Windows 11 Home
• Version: installed 0.8.11, but console output shows 0.8.10
• Godot Version: 4.4 stable
• Type: godot-rapier-2d-single-simd-parallel
