So for example, I shift drag a layer mask from a layer near the bottom of the stack onto a layer near the top. The whole stack of layers jumps up and the layer I just dragged a mask onto has now slid up and not visible in the layer panel. I have no way of visually confirming that the mask I've added has been applied to the correct layer as I can't see it anymore!
It also happens both option-dragging layers and I've noticed that sometimes it doesn't jump around when option-dragging but then jumps immediately after I undo.
I really hope this is not somehow a feature as I can't think of a situation where this is useful.
This is OS X specific.
