The switcher (Alt+Tab) is showing incorrect windows after using Deskop Wall (Ctrl+alt+<direction>)

[Brandon Schaefer]

After using Desktop wall and then pressing Alt+Tab quickly the switcher shows incorrect windows. The switcher uses the previous workspaces for its windows.

Video posted below:

Reproduce:
Start at workspace 1
press: Ctrl+Alt+Right
press: Alt+Tab right after switching workspaces

Outcome:
Switcher opens with incorrect windows (Windows are from Workspace 1)

Expected outcome:
Switcher shows correct windows for the correct workspace.

(Also note I do not have a Show Desktop icon in the Switcher. A new option was added to remove that :) )
