A Shaper Group keeps its original shapes as a transparent first child.
Clicks skip them outside Construction mode, but a marquee did not: one
drawn over the outline of an original shape whose face the group had
erased selected the group, where nothing is shown. Group Selection's E
marquee selected an original shape that lay inside it, and Direct
Selection's marquee and clicks selected the anchor points of the
original shapes.
The marquee now skips a Shaper Group's original shapes with the same
check clicks use, which moves into shaper_hides, and Direct Selection's
walk over the art it can pick skips them too. In Construction mode, with
the original shapes isolated, the marquee still selects them and Direct
Selection still selects their anchor points.
