    window: Do not unfocus on new window
    
    mutter would remove focus from a toplevel when showing one of its
    transient window which is not on top and not focused.
    
    When using xdg_popup without grab as allowed in xdg_shell v6, the popup
    wouldn't be focused, and if an intermediate event occurs before the
    popup is shown, it's not placed on top either, which could randomly
    trigger a loss of focus in the corresponding toplevel window.
    
    Remove that special case, it doesn't make much sense to globally unset
    focus when mapping a new window.
