    allView: Always update currentPage
    
    Commit 0f178c3b3dcfe added a shortcirtuit to avoid running
    an animation on an invisible actor. However, it introduced
    a bug where the current page is not properly updated. That
    leads to the wrong set of icons being animated under some
    circumstances.
    
    Update the current page even if we bail out early.
