A collision destroy event between objects without `z()` causes collision events to be repeatedly triggered for other components with `z()`.

[luluxia]

As shown in the console of this [demo](https://jsfiddle.net/dar90uok/2/), the collision event between object1 and object2 is repeatedly triggered, and if you remove z() from object1 or add z() to object3 or object4, it will return to normal.
