I'm not sure why this happens, but when the parent element has perspective declared this causes the overlay and helper layers to be stacked on top of the desired target, instead of underneath.
I think this, too, would cause a new stacking context, like opacity, transform, z-index, etc. We could add this to the list of attributes to check.
