    workspaceThumbnails: Immediately initialize should-show
    
    At the moment, we only get the initial :should-show value when populating
    the thumbnails. That only happens when entering the overview, so any
    listeners to notify::should-show will perceive it as a change rather
    than an initialization, which can result in unwanted transitions.
