Bug? (move the painted and selected area with multiple layers selected)

[Nisino]

Please check this.

Paint something on multiple layers.
Select the multiple layers in “Layer Panel”.
Select the painted area by “Lasso Tool”.
Move the painted and selected area by “Move Tool”.

All contents painted with multiple layers move.
The selected area is ignored.
I want to move only the selected area with multiple layers.

This is not a bug. This works like in other similar apps.
Moving selected area works only when only one layer is active.
