Collider::compound from an ellipse doesn't work correctly

Description

Collider::compound from an ellipse collider doesn't register (at least some) collisions.

Example

Below code spawns a compound collider consisting of a single ellipse and a square. The two shapes are overlapping at spawn, so that should be printed, and shapes should be moved to be disjoint. Neither of these happen.

If I use Circle::new(100.0) instead of the ellipse, everything works as expected - I get a message about entities overlapping at spawn, and the shapes are moved to no longer overlap.
