Thanks so much for finding this work-around! I got it to work with my
application (soon to be put somewhere public). I didn't think to use both
action triggers to make things fire sequentially and would have guessed
that the <$button actions> would execute second. It still seems like
something isn't right here. I did not see the double actions that you
witnessed or maybe, in my case, it really didn't matter if the same tag was
(re)added twice.
