I encountered a crash while updating bevy_rapier, and tracked it to this fix.

It would be worth verifying the rest of the logic, and add more tests.

Reproduce on dimforge/bevy_rapier@af92a92: run cargo run --example testbed2 -> change example to ropejoint2 (but any other demo change will trigger the crash)
