In the clip I am selecting all three reddish parts, doing ctrl+D(cloning them), and then attempting to drag my newly cloned and selected parts around. As you can see, it ignores my selection and instead selects the brick I click on. I don’t believe this is the behavior that is intended.
In the second part of the clip I am ctrl+V(copy pasting) the bluish parts and they allow me to immediately drag them around. This is the behavior I believe is intended with ctrl+D
