Collision detection anomalies

1.When initialized, it cannot be moved when the moving object is larger than other objects.
2.When a moving object jumps, it can overlap with other objects.

I guess it may be the problem caused by taking a collision using radiographic detection.

I noticed that this example also uses an octree for collision detection, and the effect is excellent, and I have found no problems so far, I don't know if it helps this bug.
