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 Pager widget 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. Enable Show window outlines in the Pager widget configuration
3. Open a window and quick-tile it to the top-right
4. Pin it to all desktops (de-syncing the window's position on the two desktops)
5. Click back and forth between the two desktops in the Pager widget

OBSERVED RESULT
The widget shows the window to be in the same position on both desktops, choosing whichever position it has on the active virtual desktop. When switching desktops, the window's outline moves on both desktops.

EXPECTED RESULT
The widget shows the current window position on each desktop.
