I believe another example of this is when using the Chromium Hangouts extension[1]. The extension uses Chromium Panels - small windows anchored to the edge of the screen that appear on all workspaces - and those panels have the same effect. See "Panels window causes Workspace switching focus to break"[2] for more.
