    boxPointer: Do not mute key events while showing
    
    We want to mute things like pointers hovering the BoxPointer while
    it does open. However keyboard events should still be handled
    promptly.
    
    Since Clutter.grab() will involve different actors being grabbed
    and focused, this will have some more presence, e.g. when navigating
    panel menus. We want to be able to navigate outside a menu while it
    is still being shown.
