    allView: Ensure event blocker is reactive before popup is open
    
    The event blocker in AllView is responsible for stealing click events
    from the icon grid and closing the folder popup. The event blocker is
    kept unreactive when no folder popup is visible, and it's made reactive
    as a response to the 'open-state-changed' signal.
    
    Using this signal, though, is problematic. When opening an app folder,
    the icon grid first opens space for the folder to fit in; during this
    period, it's possible to click on another folder icon, and break the
    icon grid state.
    
    Make sure the event blocker is reactive immediately after clicking on
    a folder icon.
