CALayer rotation on Y axis ignores z position

Question

Hi,

i have some CALayers one on top of the other with different z-values. the z-values are sequential (1,2,3 ...). i wrote some code that changes the y-rotation of a CALayer when i click on it. the y-rotations changes to -30.f

the problem is that when i click on a CALayer it rotates and goes behind the CALayers that are actually beneath it (by z-value ordering).

i understand that changing the y-rotation by -30.f actually takes the CALayer back in a sense. but shouldn't it consider the z-value as the index of the CALayer in the container and make sure it stays on top of lower z-values ?
