    messageList: Fix invisible close buttons still working
    
    Since commit c4f2bb5f, close buttons are hidden by making them fully
    transparent rather than setting their visibility to false to keep
    the overall message layout stable. As a result, the buttons now work
    even when invisible, which is clearly unexpected - fix this by updating
    the reactive property appropriately.
