Revert 124385 - Allows tab dragging when maximized on aura. To fix it I made it so
that you can drag a maximized window when tab dragging and no
constraints are imposed on the window. Only when the mouse is released
do we do anything. This only handles the multiple tab case, if you've
selected all the tabs in a maximized window we won't detach.
