rotated angle of group layer using script
We have a rotated group layer like below.

And trying to get the rotated angle of group layer from script. But while i cannot find any APIs to retrieve the angle. I tried to calculate the angle using corners from "r-bin" post for getting angle from Smart Objects(Thanks r-bin and JJack). But for group layers, current value of corners are returned when using layer.bounds().

In this case, how can we get or calculate the rotated angle of group layer?
Thanks in advance
