Hello, I found this weird issue with the following configuration:
I have a few balls bouncing around in a contained square (the container is made up of 4 planes) like so:
I then fire a few balls that go very fast, and when the balls intersect each other, they get stuck between said balls. And the weird thing is that I set my collision masks explicitly to avoid having balls colliding with each other :/

They bounce around fine against the walls, so no problems there.
Then if I remove the line 'ccdSpeedThreshold: 0' to disable CCD, they work fine, and the balls don't get stuck anymore when they collide with each other. Am I missing something? I would upload a test case but unfortunately I have this integrated with a complex system running threejs for the visualization... but here is a screenshot with the balls stuck:
