As I understand, you can move a single object on a vector layer but you can't move a group of objects. I thought this could be a bug.

1. (on a vector layer) create and then move two shapes, one at a time
2. click-and-drag to select both shapes, and make a group
3. try to move the group of shapes

Actual result: you can't drag the grouped shapes.
Expected result: you should be able to move the whole group.
