    display: Don't focus the no-focus-window when sending WM_TAKE_FOCUS to a globally active window
    
    Clients like on-screen keyboards try not to take focus when the user clicks
    on their window by setting the Input hint to false. However, due to GTK+ and
    GDK bugs, the public API for setting the Input hint to false don't remove
    WM_TAKE_FOCUS from WM_PROTOCOLS, unintentionally putting them into Globally
    Active mode.
    
    These clients also expect that since they don't want to take focus, they want
    the focus to remain on the existing window. In this case, for clients like
    on-screen keyboards, it's so they can send synthesized keyboard events to the
    focused window.
