No Messages Until Scroll

Is this a bug or expected behavior? I guess I have never seen it because
when I create the scroller I always set the v/h scroll to something even if
it's zeros.

Yes, I've run into this, or something related to it.  It seems that controls
within a scrolling group are non-responsive until the group has been
scrolled (or received some scroll message).  A workaround that seems to get
things going is, after creating the scroller, set the scroll value of the
scroller to some value, like 0 or its current scroll value.  Once this value
has been set, controls respond to mouse/touch events.
