Display settings confirmation dialog appears out of the screen when disabling one monitor in a multi monitor setup

I have a two monitors setup with the laptop screen and external monitor connected via VGA. This setup is illustrated in the attached screenshot from the display settings applet in the control center.

* Taking that setup as a starting point,
* Place the display settings window on laptop monitor ("bottom" display)
* Click on the "off" button for the laptop monitor to disable it
* Click the "apply" button to confirm settings

Expected result:
* Laptop monitor turns off
* Display settings window moves to the current workspace on the active monitor
* Popup dialog asking if I want to keep this configuration or revert it appears on same workspace as above

Current result:
* Laptop monitor turns off
* Display settings window and popup dialog move to the workspace "down" from the currently active one

In other words what is happening is that the windows that were in a disabled monitor gets moved to a workspace that has the same relation to the current one as the spatial relationship between monitors. For example if the laptop monitor was setup as being on the right of the external monitor, the window would be on the workspace to the right of the active one.

This is clever, but extremely hard to guess for the user, especially if they don't normally use workspaces in their daily ubuntu usage.

What's worse is that there's a timeout on the confirmation dialog that will keep ticking and will automatically revert the previous configuration when it expires, confusing the user even more.

I don't mind keeping the clever behaviour but the display settings window should be an exception to that rule and should always appear on the active workspace on the active monitor. Or the workspace should switch automatically to the one where the window ends up being placed in.
