This is inspired by the GNOME Overview. The top bar, where the workspaces with their previews are drawn, currently serves only to focus a workspace. So the workflow to drag a window from workspace A to workspace C, while currently focused on workspace B is to:
1. Click on workspace A
2. Reopen the overview
or
Use the Desktop Grid. 

STEPS TO REPRODUCE
1. Open overview
2. Try to drag the previewed window in workspace
3. 

OBSERVED RESULT

Nothing happens.

EXPECTED RESULT

The window, that is being previewed (so far I have noticed that it is always just 1 window) gets dragged to wherever I want it to.
