If the panel is only shown in the overview, it currently slides in from the top. Especially with touch gestures, this feels a bit off, as the panel movement is not in sync with the workspace movement. This MR re-attaches the panel to the
overviewGroup if hidden and removes all easing. Hence, the panel is rendered behind the workspaces like the Dash, the Workspace Overview and the Search Bar.
