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.
