I can confirm this happens. This has nothing to do with workspaces from the users perspective. Opening a browser window and any other app windows ― Chrome won't be shown in the list of alt-tab. Also only having Chrome opened doesn't show any list on pressing alt-tab.
This is a serious usability bug either on the Ubuntu or Chromium end.
