Setting gravity through PhysicsServer2d not working

[dredawkins11]

Describe the bug
When setting the gravity at runtime through PhysicsServer2D, nothing happens. With the exact same setup, switching back to GodotPhysics, the gravity is changed as expected. I'm not sure if there is a way to change the gravity through a different part of the API, so if that could be provided, I'd be grateful.

To Reproduce

1. Create new project
2. Add a physics body that would be affected by gravity
3. In a script add: PhysicsServer2D.area_set_param(get_viewport().find_world_2d().space, PhysicsServer2D.AREA_PARAM_GRAVITY, 0) (the code suggested by Godot docs)

Expected behavior
The gravity should change to the value (in my case 0) through use of the normal Godot API
