    application: Stop updating previewer on windows focus
    
    It is a very specific corner case when the previewer (sushi) is
    being used alongside multiple windows of Nautilus.
    
    This causes a race condition when the change of active-window
    notification arrives out of order with the check for the previewer
    "Visible" property, making the update process loop when previewing
    videos.
    
    Fixes #1823
    
    
    (cherry picked from commit 0b7a7f95f84f775be38e5533a37f93567fba2b59)
