Why did you want to use a before-string? why not simply a single
invisible character before the button? It sounds like an unnecessary
complication to me, since before-strings and after-strings are
inherently tricky, even when they aren't invisible.
But if you want me to look into this, you know what to do: show me a
short Lisp recipe which I could investigate.
