Out of sync window positions when pinned and tiled

SUMMARY
A window that has been pinned to multiple virtual desktops and tiled, causing it to be able to be in different locations on each desktop, shows up in the Overview as if it's in the active desktop's position on all desktops.

STEPS TO REPRODUCE
1. Set up two virtual desktops, side-by-side
2. Open a window and quick-tile it to the top-right
3. Pin it to all desktops (de-syncing the window's position on the two desktops)
4. Open the Overview

OBSERVED RESULT
The window is shown in the virtual desktops preview at the top as being in the same position on both desktops, choosing whichever position it has on the active virtual desktop. When switching desktops, the window's preview moves on both desktops.

EXPECTED RESULT
The window is shown in its current actual position on each desktop.
