Collisions do not work when the Collider is inside the hollow ring

[shenopkss]

I'm experiencing an issue where collisions do not work when a Collider is inside a hollow ring. The dynamic rigid body passes through the hollow ring without detecting any collision. I hope someone can help me, thank you very much!

Here is the code demonstrating the issue:

commands.spawn((
    RigidBody::Dynamic,
    Collider::circle(radius),
    MaterialMesh2dBundle {
        mesh: Mesh2dHandle(meshes.add(Circle { radius })),
        material: materials.add(color),
        transform: Transform::from_xyz(0.0, 0.0, 0.0),
        ..default()
    },
));

let outer_radius = 50.0;
let inner_radius = 40.0;

let shapes = vec![
    (Isometry::identity(), SharedShape::ball(outer_radius)),
    (Isometry::identity(), SharedShape::ball(inner_radius)),
];

let hollow_ring = SharedShape::compound(shapes);

commands.spawn((
    RigidBody::Static,
    Collider::from(hollow_ring),
    MaterialMesh2dBundle {
        material: materials.add(color),
        transform: Transform::from_xyz(0.0, 0.0, 0.0),
        ..default()
    },
));

Expected Behavior:

The dynamic collider should detect collisions with the hollow ring and not pass through it.

Actual Behavior:

Collisions are not detected when the collider is inside the hollow ring.

Additional Information:

Any insights or solutions to this issue would be greatly appreciated!
