-webkit-box-reflect: brings an image to the front, even if it has a lower z-index than other elements.

Hi,

From this sample i can see that the elements have static position. The CSS spec says that z-index works with positioned elements (those elements that have position: absolute|fixed). In this sample, if one specifies absolute positioning, then WebKit behaves correctly (i have tried with nightly 86041 on Mac). 

In my opinion, this is not a bug.

Regards,
Mihnea

Ok

-webkit-box-reflect cause an element to become a stacking context, so this is correct behavior.
